Especially those one that include lots of C4 and the like.

No trouble role-playing, but heck, are there a lot of options to consider for what my characters would do.

There are different kinds of evil.

There is the psychopath evil for example. who would have no problem cutting a baby in half and throw one half to his mother just because he feels joy from others suffering.
There is the selfish evil. He does not always resort to violence unless there is some kind of self-interest for him. He is just cruel. Instead of killing the baby, he would kidnap the baby and turn him into a serial killer.

Then there is the evil person with a code. He follows it strictly. For example he kills people for his God (like the crusader) But he would never nuke Megaton.

Here are the nine D&D alignments and what they mean:

* Lawful Good (Crusader) - Loyal, hard-working members of the community, or truthful and honourable fighters against evil who hate to see bad go unpunished. They believe that having an ordered society is the best way to further the common good. Example: King Arthur.
* Neutral Good (Benefactor) - They believe that a balance somewhere between total order and total chaos is best, and would generally concentrate on doing the morally right thing without worrying about whether it was good or bad for 'society'. Example: Mother Theresa.
* Chaotic Good (Rebel) - Strong believers in freedom who like to make their own way and hate people who bully other people and try to push them around. They will often have a strong moral code which may not agree with the law. Example: Robin Hood.
* Lawful Neutral (Judge) - They are disciplined and believe that adhering to and enforcing laws and traditions is the most important thing. They will not generally go out of their way to help others but will intervene to stop crime. Example: Asimovian robots.
* True Neutral (Undecided or Balanced) - This can mean either of two things, depending on whether the character is actively or passively neutral. Active neutrals (the Balanced type) are very rare. They are philosophically committed to maintaining the Balance, and will tend to join every fight on the losing side. Passive neutrals (the Undecided type) are somewhere in the middle on both the Good-Evil and Law-Chaos axes. The passive neutral alignment can also apply to creatures with no moral sense such as animals. Example: Zen masters (Balanced), animals (Undecided).
* Chaotic Neutral (Free Spirit) - A strange and very rare alignment. Chaotic neutral characters are very unpredictable individualists, being governed by whatever they feel like doing at the moment. Example: Calvin (from Calvin and Hobbes).
* Lawful Evil (Dominator) - They respect the law, but have no concern for others, and tend to exploit the law to rise to power. Often they will engage in merciless, organised, planned killing. Example: Adolf Hitler.
* Neutral Evil (Malefactor) - A purely selfish type, with no concern for other people or the law, but without as much lust for killing as Chaotic Evil characters. Example: Case (from Neuromancer by William Gibson).
* Chaotic Evil (Destroyer) - The most dangerous characters of all, they will rove around killing and destroying for the sheer joy of it. Example: orcs.

If all that was too long and confusing, D&D Adventures has a short explanation of each alignment in terms of 'I'll kill you because...' If you are playing a pacifist character, or just trying to determine your real-life alignment as an ordinary person who has never killed anyone, you might prefer the descriptions below in terms of 'I'll heal you because...'

* Lawful Good - society is better off when people help each other.
* Neutral Good - you need it.
* Chaotic Good - I want to get back at the uncaring society that left you to die.
* Lawful Neutral - the law obliges me to.
* True Neutral - you'd do the same for me (for the Undecided true neutrals, by anology with them killing in self-defence at the website above) or you are the underdog (for the Balanced true neutrals who join every fight on the losing side).
* Chaotic Neutral - I feel like it.
* Lawful Evil - you are vital to my conquest of the world.
* Neutral Evil - there's a nice reward for it.
* Chaotic Evil - I want to torture you more before you die.

A psychopath is not aware of what they are doing, but is usually acting out a sort of delusion.... you are thinking of a sociopath who knows what they are doing and more specifically a sadist who not only harms people but likes to really rub it in.

I'm a good character and find it hard to be evil. Only exceptions for wanting to be evil are when you see some funny comebacks in dialogue and . . .

What about turning the kid into a killer then ransoming him back to the mother to get profit and then sit and watch the blood and gore to follow as the kid does what he was taught.

But what if my god told me to blow up Megaton. And not all Gods are good or evil.

I only do evil stuff when i meet npcs and they're plain rude to me. i save then pumpthem full of shotgun shells, reload the game and walk away from them

I think it's the NCR Face-armor thing (I got it, but sold it.. 29 lbs for a half-mask????? HELL NO... even if it IS like DT 9)

It's a full body suit IIRC.

I always seem to find my self going good guy too, but I did piss off the dude with the blue star cap neck-less so he would attack me, I wanted those caps what can I say :shrug: ..........oh and executed the Powder ganger's that were tied up in the legion camp, because I'm there grim f*%$@#g reaper :rofl: still the best line someone has said to me yet.

bigcrazewolf

lol i killed everybody that come's in my path of total destruction

I usually end up playing a "good" guy, but in Fallout games I start to lean towards the "western justice" end of the scale.

I guess after a while I just don't like to be called a ****weed and my solution is pretty messy. :celebration:

I'm the same way. I always end up playing the same in Bethesda games no matter if I'm trying to play evil or not. I just can't keep the evil thing up. It's draining. It's too contrary to my normal viewpoint. The fact that that even bothers me means they do a good job with these games because in other games I don't even pause before mowing down civilians.

I remember trying to do an evil playthrough in FO3. I did it for a while then got to the stealing independence quest. I go through the whole thing with Sydney, know her background from a previous playthrough but I wanted her gun. After the quest we're out on the steps and after saying goodbye I wait for her to turn and blast her head off. I felt so oddly bad about that I left the gun there and gave up on an evil playthrough.

I have this problem in most games. The one exception is the KOTOR games, because the Dark Side responses in conversations are just so hilarious.

I typically play as chaotic evil and I play Fallouts as though we had had a nuclear war. I am more selfish in game than I am in real life. I will steal your stuff, kill you if you threaten me etc.
I tried to play FO3 evil and I couldn't manage. I blew up megaton, then regretted it almost immediately. I kept going though, rather than reloading. I couldn't do the slave quests. I wound up being the savior of the wasteland (or whatever the highest moral level was) simply because it made me feel like crap to be evil.
On the otherhand, I could repeatedly take out everyone in megaton and reload. Not a problem so long as I didn't have to live with the consequences: dead town.
In Fable 2 I could play evil: kill all the annoying idiots, but I HATED living with what I had done to the world. The negative impact I had. The oldtown area: damn. The place with the priests of light. Ouch. I had fun killing the townspeople but hated the dead town. Fun if it's like a dream. svcks if it's permanent.

And everytime I dealt with the extra loading screens to get to my hotel room, I was reminded of megaton, and I regretted killing it. Seeing Moria just svcked.
