General Discussion

As a general rule, I don't think the death penalty should be applicable, largely because the justice system is fallible. If you put someone in prison by mistake, you can at least let them out again. They can never be truly made whole, particularly if they missed a lot of time with family while they were imprisoned, but they can be freed. Not so with someone who's been wrongfully executed.

That said, for some particularly heinous crimes, if proof of guilt is absolutely incontrovertible, I won't feel all that bad if the perpetrator gets the death penalty. By "absolutely incontrovertible" I mean that there is utterly zero possibility that this person is innocent due to the totality of the evidence. This alignment of requirements would be comparatively rare, but I can tolerate the death penalty if that's the scenario.
