Uh i'm pretty sure Akatosh is a good god- a divine- and not the nordic god. But thats a good point- if His servants must be killed, at least don't blame them for trying to kill you. And unfortunately, i don't have the time or money to play WOW as its rather addictive.
There's no such thing as a good god or a bad god. The only reason the nine are worshiped is because we cut a deal with them a long time ago. They help us, we give them power through faith. They don't help us because they think its the right thing to do. They help us because we're their energy source. Ya, the aedra are better than the daedra, but not by much.
And think of Alduin as time itself rather than a dragon or a being we can simply understand. He consists of a beginning, a middle, and an end. Without him, things are just there. New people, places, and things don't exist, because there is no such thing as a beginning or new/old. With him however, even though things can begin, they must also then end. And guess what?
...Nirn's timer just went off.
Alduin doesn't hate us. Probably doesn't like us per say, but he doesn't hate us. It just so happens that he's tied to Nirn, cause when Nirn was made Lolkharn tricked him into giving up his energy along with a lot of other aedra's energy to make the place, thus resulting in them being trapped there. See those stars? That's some of the aedra who got the heck out of dodge before it was to late. Alduin on the other hand didn't, and is stuck here till Nirn goes away. Once the dragons get rid of Nirn, they can go home. They're not evil, just between a rock and a hard place. And it just so happens that we're up here killing off each other in a civil war while Alduin has to watch.
He's probably a little pissed about that. So here they come to eat us, because they finally have gotten sick of us being the only thing inbetween them going home.
Its very gray. Which side is right? Neither in all honesty. So if you don't want to kill em, Nirn will be eaten and all the people around you will die. That's what we face. A question with no right answer. Either way, there will be blood on your hands.
