I guess it depends on what your reasoning is. If you are using the death penalty as a deterrent, well...you're shit out of luck. It doesn't work. It never has. The people that commit these crimes are

A. Completely reckless with no understanding of consequences.

B. Idiots who think they are going to get away with it.

C. Megalomaniacs who think they are too smart to get caught. (Some B are C. Some B are not non-C. Some B are not C.)

It just doesn't work as a deterrent. However, if you wish to be honest with yourself and call righteous vengeance then I have few problems with your attitude towards these people. However, the justice system isn't perfect and occasionally we get the wrong man, only to discover this ten years later. So, I can support the feeling but not the policy.
