Who is arguing that people want to make everything he does perfectly justifiable? No one has said that in either this thread or in other threads. I mean really, you're just building up a straw man argument here and beating it down and not actually adressing the points that people are actually making.

And you know, some of us prefer villians that are more than two dimensional. Complex villians make for a much more interesting story than guys that are just crazy and paranoid. Two people with confiliting views that are both shades of grey is far more compelling conflict than one person being 100% right and the other 100% wrong. Stories where Loghain is totally wrong, evil, incompetant and other opposing characters, such as the warden, are 100% right in what they do are not only boring but sadly simplifying his character.
