I think you are interpreting my first post differently then my intent. My point is 3300 years ago or more there was problem with psychopathic behavior. It is an inherent problem throughout all of history. I’m not giving anyone a free pass. God cused Cain but let him live and made sure no one else killed him.
I don’t believe mentally ill people can cure themseves by deciding not to be ill. Just like a cancer patient cannot cure themsevles by deciding not to have cancer. Cancer patients try that everyday. That is not part of “free will”
