So you kill 4 peole write a few books and that makes you elgible for clemency? Right! I think not! He mimicked the guy dying in one of the killings!
Not to mention, he STILL isn't accepting responsibility for his crimes. The old "It wasn't me" defense. If he were truly reformed, he would admit it, and ask for mercy.
This guy is a waste of skin, and needs to be gone, period.
