On a serious note, I'm split on the death penalty.  Over my life I've changed my stance on this issue multiple times.  So much of the time, it would depend on the crime.  A few examples:

 

...kill and rape children & teenagers?  Boil them alive in a vat of oil.

 

...kill and/or rape women (or men)?  Electric chair or lethal injection.

 

...kill someone who slept with your spouse, or kill your spouse for cheating on you?  Probably life in prison.

 

...kill someone who raped or killed a relative of yours?  Maybe 10 years in prison with early parole for good behavior.
