I wonder if there's a generational difference. I believe I'm rather older (age 57) than the typical LessWronger.

Opponents to capital punishment, like Geoffrey Robertson QC, argue that it is "much worse for an individual to spend the rest of their life in prison than to be executed immediately"

That's the only example I've been able to find in about 15 minutes of googling (and British, not American), so it may be a less common view than I thought. Or maybe I don't have the right search terms.
