I see where you're coming from and I do somewhat agree, but in the end I think they should be kept alive as it is more often than not a more harsher punishment for them in the end.
Well not necessarily. The people who commit huge offences such as serial killing or war crimes will more than likely be content with what they have done and so will not feel 'pain' by being punished for doing this (at least, not if the punishment is being put in prison).
Death is a cold punishment, but in a way it isn't actually a punishment. They aren't tortured to death, rather they don't feel a thing. Is this really being punished? In my opinion no, because they are not alive afterwards to experience their death. In effect they actually have no experience of being punished. So what's the use?
In the end, the only reason there is to kill someone for their crimes is to fullfill personal 'satisfaction', if you can call it that.
