I disagree. The man sadistically murdered the ate his victims. He deserved the death penalty BIG TIME. If the State wasn't willing to do their job ... then an inmate did it for them.Going to prison for what he did is justice.
Being murdered in prison by a fellow murderer is not.
The tragedy of Dahmner is that racist cops ignored pleas from the community that there was something seriously wrong there. Several murders COULD have been prevented had the police taken more serious action. In one case, they actually returned a 14 year old boy to Dahmner's custody (who was subsequently murdered.)
But back to the point, you seem to want your imaginary sky friend to murder people who don't share your values... that seem "harsh".
Wow, I always find it amazing that so many Christians miss Jesus' point.
