I believe capital punishment is a right thing to do. I believe this because if they have done something so terrible that people even have to consider killing them, then it should probably be done.
People they have hurt would probably want this done too because they have been affected/hurt by these people and their actions. Hanging though, is a rather durastic and medieval thing to do.
The electric chair, I believe, is an "alright" thing to do because, again, if they have been stupid enough to do the terrible things they have done, then be it far from me to decide whether 100,000 volts are shocked through their system or not.
