No, I don't think it absolves him of blame, but I think he thinks it does. Each personna sees their actions as completely justified and right. Righting a wrong, dispensing justice in the good old "eye for an eye" method Then that personna sheds its skin, like a snake does, and moves on to the next one. With each personna change the deeds of the one before are forgotten, absolved, done by someone else. It's never the "real" him that does them because that person never actually does anything and is therefore blameless.
