I liked his character, and seriously applaud the writer who created him. I think he represents a lot of the desperation that can push a person to do horrendous things, and it's sad in this case because Anders was a likable guy who I probably would have gotten along with famously in real life. He was funny, he had a big heart, and even had a surprising amount of control despite the state he was in. I think he had a lot of strength and I was constantly worried about the obsession he had with justice for the mages, especially since he acknowledged that Justice had changed to a force of Vengeance inside him. Even though he and Justice had essentially merged into one being (as he claimed), I had hoped the entire way through that the better side of him would win out. That's why when he desolated all of those people and became that which he despised - one who harmed and murdered innocents - I felt the betrayal in the deepest part of my heart and I had to step away from the game for a bit. No cause is worth something as terrible as mass murdering, and nothing can condone it. After all my Hawke fought for, it made me SO angry.
Even so, I couldn't kill him. I wanted to, but I just couldn't do it. Not only was he my friend, but if I did that it would have neither helped anyone still alive nor would it have fixed the situation. It wouldn't have made me any better than him, and it wouldn't have solved my problems. So I kept him alive. I wanted him to see what came from his actions, I wanted him to do anything and everything he could to make up for this disaster, even though he probably never could. Killing him would have been a mercy, and that is something he did not give those who died for his justice. I mean, how dare he ask for that? Seriously?
I told him to leave, and when showed up at the Gallows to fight for the mages, I told him he could stay and fight for them. He owed them AT LEAST that much. I didn't forgive him, I didn't condone his actions, and I expect him to spend the rest of his life paying for what he did. But... I still don't hate him. He made me so angry because I liked him that much, and I'm anxious to see if he'll make him an appearance in DAI. I want to know what he's done with the life I had him keep.
Sorry for the speech. Long story short, I appreciate the value he had in the story and applaud all the turmoil he creates as a character. And dang it, as much as I want to hate him I can't. I like him so much that I'm gonna be angry at him for the rest of my existence. *sigh*
