Deserves it! I daresay he does. Many that live deserve death. And some that die deserve life. Can you give it to them? Then do not be too eager to deal out death in judgement. For even the very wise cannot see all ends.
I don't believe in God. I don't believe that even a hypothetical supreme being with ultimate power over life and death is a beneficent moral construct. I certainly don't believe that we humans should seek to emulate that being, whether we are regarded as criminals or as officers of justice for doing so.
