Had he been in texas he would've died 23 years ago.

Moving on...I think it's clear that redemption is possible. The environment he was raised in led to the rise of that monster, he did terrible things out of desperation, and an attempt to rise above the rest. Killing those people, no matter the circumstance, is unforgiveable.
It is a tragedy, not because he shouldn't have been severly punished, but because he rised to meet his fate, reached out as far as he could, and held onto what he had and gained within himself as long as possible. While some people may mourn his death, or asked that he should be put in prison for the rest of his life. I think he was probably unafraid to die, he knew later on in life, that the consequences of his actions would hound him with guilt and misery until the day he died.If I was in his position, I would be prepared to face my final judgement. And if there is a god, or an afterlife... undoubtedly he will not be damned for eternity. He already made reparations. And I hope that somewhere, he will be at peace with himself for the rest of existance.
