[Yokuutsu]

Well, in Dragon Age, it's either people are doing bad things and you're stopping them...or something is ruining the world in general....dark spawn and the taint and the blight that comes along with it....demons and stuff from the fade causing chaos...parent trusting a blood mage to teach their child instead of sending him to the circle and so he gets possessed by a demon....the qunari causing some chaos...dude putting people together out of parts after killing people that the parts came from. Darkspawn that can be reasoned with, but can still cause the taint and blight but want to change things. Fun stuff like that.

Remember, killing doesn't have to be justified...not everyone kills for a reason.
