I would say the biggest factor in his change recently would be Baggage City. I shudder everytime I read that arc. Anyways, it was the first time that his actions had led to the deaths of multiple people that he couldn't save even though he was there. The tragedy there was hellish, to put it in simple terms. The fact that his actions had led to the deaths of so many would have darken his perspectives a lot I would say.
