this could be really basic but i don't know, so; Why are the Chaos gods evil? ARE they evil or just misunderstood?
i mean the Necrons hate all life and want to stop it but thats only an evil motive if you assume living = good. the Chaos on the other hand doesn't seem to have any motive at all. they just pure evil. which doesn't makes sense.
does GW anywhere explains the purpuse, motives and goals for the Chaos except stating that they are the ultimate evil?
this really interested me too so i read a bit about it a while ago(i havent read too much about the fluff so take this with a grain of salt
I think i read that the warp (and the chaos gods as a consequence) are strongly influenced by the emotions of sentient creatures(not orks and tau). Once when there was no or almost no higher evolved life the warp was calm. But as civilisations grew and populations rose their imprint on the warp increased as well. What menas: emotions(good or bad) fuel the beings of the warp. The more emotions of a certain kind amass in the materium the more "fuel" the beings of the warp connected to it get and the more powerful they become.
The eldar(as psychers with a strong warp presence) started their great fall to decadence and polluted the warp with hatred, sadism and insanity until they created a new god connected to the crazy marquis-de-sade-lifestyle they had led (most of them died and the rest lives an incredibly disciplined live to minimise their impact on the warp...and not to get their souls eaten by said god).
Humans leave a way smaller imprint on the warp but there's trillions of them, living in a totalitarian system full of religious fanatics with suffering, greed and war all around them. OM NOM NOM for chaos.
According to the starting thesis, when humans would try to live lives of discipline and peace controlling their emotions the would no longer fuel the malign energies of the warp. Maybe the warp would even calm a bit, there were less daemons and the 'evil' chaos gods would loose their power. the 4 greater powers could the gods of hope, honour, love and permanence once again.
Well but that is quite impossible I think. the imperium cannot change itself to such extent. It needs to keep that form to survie, what would mean (oh the irony!) the longer it holds out aginst chaos and the more desperatly it fights for survival the more powerful the negative sides of the warp become.
I think the Necron have a simliar approach to this.
Chaos(the polluted immaterium)

owered by the emotion of (sentient) life
plan of action:
1) kill all sentient life
2)kill flowers, moss and bacteria, just to be sure
3)the warp is calm again
4)profit!
And thanks for the fast answers to my last post!
