LH, Mudcat can boast a former cop who also studied theology and whom I assume to agree with me that there is no clear line between "essentially good" and "seriously disturbed". Actually, the closer you look, the less visible the difference. Criminal law, police, prisons, and psychiatric wards are necessities of human societiy, but we should not believe that they can possibly tell the full truth about human nature. (That would remain true even if we had omniscient and absolutely unbiased judges.)
