How do you view capital punishment?
Some call it punishment, some say it is revenge.
I don't even think it should be called "punishment". I just think of it as getting rid of a problem.
If I step on a piece of broken glass on my floor, I don't put it away in a box and consider dropping it back onto my floor at some point in the future. I just throw it in the trash so it won't cut my feet ever again.
I'm not punishing it or getting revenge on it. I'm just permanently removing it from my environment.
