Normally I would plead the case that the death penalty is a cruel and barbaric anachronism, and lament that in fact it has never left.
But hearing INDIVIDUAL-1 call for its return makes me think it would suit him very well.
Personally, I'm against the death penalty unless 1) the person presents an immediate danger to others and 2) it can be proved without all doubt the person is guilty. It's been established that the US has executed innocent people and I think that is one of the worst things a nation could ever do to one of its citizens.
Number two there about sums it up for me.
I have no particular issue with the notion that some crimes are worth killing the perpetrator over. However, the system of determining whether or not the accused is guilty is a fairly flawed and faulty one. There have been people in jail for decades who've been freed because of new evidence, uncovering corruption amongst the police, lazy and overworked public defenders, etc. Once you kill a guy, though, there's no system in place for undoing the conviction and letting him be free again, perhaps with compensation due to the destroyed life he's had.
Since the legal system can't be trusted 100%, permanent solutions which can't be rolled back aren't warranted.
