I'm pretty anti-death penalty. In law school I wrote a paper on how it was unconstitutional to execute 16 & 17 year olds and a few years later, the Supreme Court agreed. I'm still pissed that I only got an A- on that paper. In any event, there are lots of reasons to oppose the death penalty - it doesn't lead to less crime, it's costly, innocent people get killed by the state, it conflicts with the idea of rehabitation, it's racist in its use, etc - and only one reason to support it - revenge.
