1. The death penalty is not cheaper than life in prison
2. It's never been a significant deterrent wherever and whenever it's been used
3. It has a long history of misuse and abuse everywhere
Capital punishment is a barbaric relic of a bygone era and has no place in the civilised world.
Ah, but Grumps too is more expensive than life in prison, has never significantly deterred anybody from anything, and is a barbaric relic of a bygone era that has no place in the civilised world. So of course he's solidaric.
I don't think he has a long history of misuse and abuse though, unless that's "substance abuse" we're talking about. Which isn't really abuse, of course - as its what these substances were made for.
