Refusing to call evil by its name doesn't make it cease to be evil. It does make it easier for evil to blind the foolish or to seduce followers to its side, though.
That very much sounds as if you are calling me foolish or evil or both. I'll just add it to the pile of insults you threw at me.
To call something "evil" is to place a judgement on them that no person is qualified to actually make, and it undermines the complexity that exists in situations and in people.
If I call Yaevinn evil for personally working to commit genocide upon humans would that give his character justice? No it wouldn't because he is a lot more then just a genocidal maniac. It's similar to Jacques if he is working to commit genocide on the non-humans, which he isn't ... necessarily.
As for Jacques. I never saw him say that, in fact I checked my walkthrough of the game. While he CAN say it( I checked other let's plays ), he doesn't necessarily do so. His viewpoints do alter depending on your choices with Alvin after all, so yes I was wrong about that when I posted earlier.
He can for instance view his powers as something that he needs to use to protect others or he can view it as something to try and control others since that's his right ( or something similar to that ).
Granted however, and I never denied this, he does really hate the nonhumans, but considering his experience with them as a child...well you can't expect anything else from him. It doesn't make it fine however, no more then Yaevin''s hatred of humans.
This is why Jacques is the best antagonist in any game for me btw, because he is shaped by YOU, the player.
