Aidan winced, shaking his head. He rubbed one eye, leaning his arms onto his knees. "It's complicated. You wanted your change, I didn't. I had a wife and a kid to go home to--I was a soldier, I had men I was responsible to, and I made the mistake of attacking a monster when I should have turned and run." There was a moment when Aidan composed himself--because the topic was still upsetting, not because Isaac had done anything wrong. "There is an inherent difference between being a werewolf and being a vampire. I believe you when you say your change helped you, and I'm happy that this Derek guy helped--but you have every chance of getting through your changes without hurting anyone innocent. I feed on human life--I have struggled with the killer inside of me for well over the equivalent of a human lifetime. I try to be better, try to politely live off bagged blood and--I always slip up. Badly." He shrugged, voice a little sad. "I am inherently evil--created to kill. Cursed. You and Josh--who would be mortified if he knew how grateful I was for him being what he is sometimes--you don't have to be. You have a choice." Aidan brushed it off with a smile and a shrug. "And I just have to keep trying."
