No, I should have been clear on this. When I say suffer, I don't mean a physical suffering, like rape or murder. I mean a suffering that he truly deserves. He took away a woman's life because he couldn't comprehend the value of life. The purpose of a punishment is to teach why what you did was wrong. If he receives the death penalty, he won't learn. Then she'd have died for nothing. By placing him in jail forever, he'd be alive, but he'd have no worth. His life would have no worth. Then, he can learn how much life has value by losing the value of his(kind of like a you don't know what you have till it's gone kind of thing) and it'd be a fitting punishment.
