I'm going for the achievement, but my character is good. How can I justify them, especially Vaermina?

Demonic Possession, you have no control over what you do in those circumstances as you are but an observer thrown to the back of your mind by the mighty Daedra.

Or just put it down to a bad hair day.

Ignore the achievement. Achievements adds nothing to the game. You probably mean Namira, not Vaermina.
In Vaermina quest you play the good guy (or the stupid one if you side with the daedra and kill the very useful follower just to get a daedric gizmo)
Daedra are evil. Except Meridia there is no reason for a good characer to do anything for them

Temporary insanity... it works in the court room, so why not here?

You didn't want them to kill you. You did bad things with a gun to your head.

I could be wrong, but I believe you can destroy the Skull of Corruption and it still counts towards that achievement.

I think you'd have a difficult time justifying why you are aiding many of the daedric princess. I suppose you could set up a vault to hide all of the artifacts in, although you still need to jump through some questionable hoops to get them. Perhaps a different character would be better suited to this achievement?

Get the wabbajack, if the authorities ask, you can say you were simply insane.

You cant really for some of them. Some of them are not very evil, i would stick to those and make an evil character for the others.

Or you could pretend you went to the shrines to desecrate them or challenge the daedra only to become overhwhelmed and bent to their will

Daedra are neither good nor evil. They are essentially a "force" personified

Water can crush a house or drown a puppy, in this way it can do evil. it can also quench your thirst or help a fish to breathe, in this way we pay our homage to water, water can also float logs to a saw mill, we can redirect it's flow, it can suspend a boat and ease transporation of materials, in this way we harness water.

Daedra are no different, most have many facets. For example Sheogorath is both prince of madness, and prince of creativity, both are facets of the same phenomena, and like water, too much creativity, can overwhelm and turn it into an unhinged mind. It can be worshipped, or fearred, it can used for good or for evil - the only difference is that you can talk to a a daedra and have it answer back, unlike water. Daedra may ask morally evil things of YOu, and that is for you to measure and balance (If the god of water said "break a dam and let my waters flow over that village, it's anathema that they hold me back!) the blood would still be on your hands if you obeyed him.

But the entity itself simply is, it has no "evil" or "good" intentions it's merely a force that does what it does.

That is almost the same comparison I used in my morality paper, (atheist majoring in theology!). Excellently put.

Not all are actually "evil", but still ... just make a new character? You don't have to do everything with the same. More fun anyways.

Ok sorry if I hijack the thread, but I have similiar question to OP.

I am playing a good guy inspired of Vigilants of Stendarr or even their member (haven't decided yet), shame we can't really join them. Anyway, they hate daedra so my character, but I am asking if it is against their rules to do the quest for Meridia? I think her sword is going to fit very good on my hero, to clean all the evil from Skyrim.

Say NO to peer pressure!

I will at one time play a Dunmer who will seek out all the Daedra quests as she will be a Daedra worshiper. She will also join the Dark Brotherhood.

Note, she will not be a nice person.

A dream perhaps? Or too much skooma?

I agree that they are neither good nor evil, but the forces/emotions they represent can easily be perceived as being evil. I think its funny that in previous TES Titles Azura was always considered good and now in Skyrim she's neutral at best even though she's trying to reclaim her star. From a deranged mage who's been killing his students.

The only ones I'd consider doable from my perspective of good would be Meridia, Azura, Vaermina (destroy the skull option), Sanguine and oddly enough Sheogorath and all of his craziness, actually helps Pelagius the Mad.

You could help out and out darker gods such as Peryite where you are basically killing disobiediant followers, but now it appears your just meddling in affairs rather than being good/evil. I suppose it hinges on your definition of good, or if the process leads you to help people. Completing Hircine's quest might be considered justice by killing the werewolf and avenging the child's death, etc.

Most of the quests are shades of gray so I think it leaves alot open for opinion.

So when you are bludgeoning the dew out of some poor shlub with a rusty ol' mace this is just a nice waterfall?

Whatever helps you sleep at night I guess.

I took some leeway with lore and created a organization like the blades, which I called the Acquisitioners. They were secretly established by Tiber Septim to acquire any dangerous artifacts, deadric or otherwise, and then store them away from the world in a secret vault. Tiber Septim was the only one outside of the organization to know it existed. After centuries the Acquisitioners have slowly begun to die out because of their almost non-existent recruitment, leaving only 9 members left in the time of skyrim. It's the duty of an Acquisitioner to do whatever possible to acquire an artifact even if they must sacrifice something or someone to do so; because if they don't then all of Nirn may be put into danger.

I rped this and it was mighty fun. I played as one of the 9 who was sent to skyrim to acquire the dragon masks before something happened, but I was captured crossing the border. When alduin attacked, I took it as my responsibility to stop him and to capture all of the dragon masks before it was too late because that is the duty of the Acquisitioners. This also justified doing some bad things to make sure the deadric artifacts didn't fall into the wrong hands.

I'm still writing the lore of the Acquisitioners and when I'm done I hope to make some mods to add them into the game.

Azura's always been portrayed as keeping up the appearance of being a nice caring prince whilst having a vengeful and petty side to her. Most of that was depicted in books though. Like http://www.imperial-library.info/content/morrowind-ancient-tales-dwemer-part-11-azura-and-box

I have only played a few of the Daedra quests. At least a couple of them either appear quite fitting to complete if you are "good" - for example Meridia, who wants to rid the world of undead. I can agree with that. There's one I've done where you can come into it with good intentions to help people, and then make a moral choice where you can resist the temptation of evil and do good.

I've stumbled upon several quest starts that either sound too shady or where I've had to do something I'm not proud of just to survive... I'm not continuing those quests with this character. But my next character, the evil power-hungry mage he will be, will surely be happy to oblige.

I'm not doing any bludgeoning - Like I said, it's up to you to decide whether to do good or evil in the name of the daedra. I decide to do good, and bludgeoning a guy to death is NOT remotely good; so I don't do it.

But the daedra that desires you to bludgeon the guy is neither. And let's be clear the bludgeoning is the means to the end; the daedra wants to corrupt the victim's wishes, to turn him away from his current daedric prince and to do so in his favoured way. Molag Bal is the god of corruption and violence afterall. He isn't saying "Oh hey I wanna make these guys feel miserable it'll be funny!". Water drowns, Molag bal corrupts; it's what they do.

I didn't do most of them on my good character but saved them for my thief/assassin. Molag Bals quest was justified because while in the basemant the other guy attacked me first, and the priest was a total nut. Also, Azura isn't bad at all. Actually, I originally did Namiras quest on my good character but I felt bad for the priest so I reloaded, told him to run, and killed all of Namiras followers. I also told Mehrunes Dagon to get lost which was hard due to the picture of how freaking huge and creepy he looked in my head O_o.

Caring and vengeance are hardly incompatible. It could be argued that Azura is the Daedric Prince of Jealousy.
And yes, she's not as nice as her PR people pretend. But at least she's ... pretty safe if you are smart and keep your trap shut. I wouldn't call her evil. (Especially by the standards of Daedric Princes!)

Nelecar disagrees, (Black Start quest line) but his master was diddling around with Azura's artifact, so what did he expect? That's a blatant challenge to her power and authority. The Septim emperors would have killed you for trying the same thing with the Amulet of Kings.

Malacath's Quest isn't really evil. Basically, just tell the Orc that he needs to do his duty. Then when he fails, finish it.

Just consider it as the ends justifying the means. If you don't get the artifacts, somebody else will - somebody who will actually use them to do the princes bidding. Even in the cases where you can destroy the artifact, destroying it only sends it back to oblivion, which merely gives the daedric prince the opportunity to send it back on their whims. If you collect the artifacts, you can put them somewhere safe where they can do no harm to the world. It can take several hundred years before an artifact naturally returns to Oblivion, so if you're so inclined, go dump them at the bottom of the ocean.
