"...you see psychopaths as human..."

This has nothing to do with whether or not I treat things, people or other things, humanely. I do not treat them humanely because they are people. I treat the most predatory creature I know, the household chicken, humanely - because I, not chickens, am humane.

It is perhaps this fundamental misunderstanding that prevents our agreement. Being humane to chickens does not prevent my killing them for my dinner. I kill them without hesitation, despite that I kill them without hatred.

I do not kill them out of hatred for them, or because they aren't kind to grasshoppers.

Neither do I approach psychopaths and their necessary treatment with hatred, although I surely do hate their cruelty. I do not become cruel to them because of their cruelty. They do not determine my treatment of them.

I do. I am not cruel. I am humane. Should psychopaths need killing and I be called upon to do it, I will do it, but I will not do so relishing the task, nor increasing their suffering out of hatred and cruelty - not because they are not cruel, but because I am not cruel.

Whether they are human or not, I am.
