BG I think killing someone to know what it feels like is the very definition of unstable.

2020, no I don't believe being unstable is an excuse, as long as they know right from wrong they should be punished. However, I think it's important to know the reasons why people kill, so that we can hope to stop similar things from happening in the future.

However I do believe killers being unstable is a reason to not have the death penalty. We are all victims of our circumstances.
