Don't misunderstand me. I don't feel sorry for him at all. Like I said, I do feel like he deserves it. I want him off the planet like everyone else. I was just saying that cases like this always bring up my uncomfortableness with capital punishment, in general.
To me, killing someone for killing someone does feel a little revengeful, but I guess it depends on how close you are to what has happened. Revenge is a very normal, human thing to feel. If he killed my family, I would want revenge, too.
Punishment, justice, revenge. I still think these are different shades of the same thing.
Personally, I think "justice" would have been better meted out if he were sentenced to live in an 8x8 concrete cell for the rest of his life, living only on ham and bacon. But I guess that sounds a little revengeful!
