What's so important to you people about being against the death penalty across the board? There's no slippery slope from Hitler to a kid who stole a loaf of bread from the bodega.
Someone like Hitler did things that were so unspeakable to so many people that he doesn't belong on the same planet as civilized people. And keeping him alive would keep Nazism alive in a sense. I would support the death penalty for Hitler and if you one of you wimps got your way and Hitler was living in some country club prison, I would go there and kill him myself.
Really, does anyone want Hitler writing Mein Kampf 2: Electric Boogaloo?
I only support life in prison if they serve schnitzel at tea time. Otherwise death penalty for sure.
