This is a weird idea, what someone "deserves" is a concept entirely made up in your head. We can talk about hard data, statistics about various punishments and their effects on factors such as crime deterrence, but there's simply no reasonable discussion to be had about what someone "deserves". I could tell you that I don't believe anyone deserves to be killed, regardless of their actions, and that is one hundred percent true to my internal morality, and that I think it's immoral to kill people to sate your violent sense of justice, but that doesn't advance this discussion in any way either.
