I'd pull the trigger on this scumbag and never lose a moment of sleep.
As would I. And pretty clearly, as would the judge if she had that option.
But what he's facing might actually be worse than that. Unless he's kept in what pretty much amounts to solitary confinement for the rest of his miserable life, some inmate will become a hero among his fellow prisoners by killing him. Even criminals have their standards, and they don't generally like child molesters.
I used to say that I was opposed to capital punishment, since I didn't think I could carry out the sentence myself, and that if I felt that way, I had no right to expect someone else to do it. And then we had two cases when I was clerking for a trial court judge where I would happily have carried out the sentence myself, so I changed my mind.
I've kind of changed it back again, since the states that carry out most of the executions seem to be completely unable to have a fair and reasonable process of deciding who gets executed and then carrying out the sentence. But that doesn't mean that I wouldn't be happy to carry it out myself on this guy, or that I won't actually be happy if some inmate gets to him with a shiv in prison.
