Which is why I believe in self defense, I also believe in evidence, there is no good pedophile, “forcible” rapist or murderer. I also tend to agree that those who use violence without cause, eg., outside of self defense repeatedly are and will remain a threat. Under strict burden of proof requirements, eg., Scots Law approach, 3 separate proofs with 3 separate proofs for each…death is a suitable response.
We will not hesitate to put a dog down for biting over and over…or other creatures. Humans should be no different.
