What should be eligible for the death penalty?

[Classicvette63]

Besides murder and treason, what should be eligible? There are two other "activities" that I think should be eligible.

Cloning or attempting to clone should be a capital offense. That would be the only deterrent. Too much down side and not nearly enough upside to even think about cloning. Just because humans are smart enough to do it doesn't mean they are smart enough to deal with it. Rich folks would abuse it and the average guy would suffer for it.

Time travel. Althought he stuff of science fiction, you know there are people working on it. Sure everyone wishes they could back and change something but we can't nor should we be able to. If anyone were able to create a "time machine" they would control the world, literally. How much power would a person have if they could say, go back to 1943 and give the nazi's plans for jet airplanes or even a nuclear bomb?

Thoughts?
