Reading "Psychiatrist Helps Court Define ‘Evil Behavior’" in the June 15 issue was wearisome indeed. In 40 years of practicing forensic psychiatry, I have never been called upon to define evil, and I hope I never will. Evil is a moral concept, the effort to give scientific validity to such concepts as "atrocious," "outrageous," and "vile" with an instrument called the Depravity Scale is junk science at its worst. These are concepts that have no place in psychiatric nomenclature. I take issue with your characterization of Michael Welner, M.D., as an "inventor" of the Depravity Scale. A more suitable term would be that he made it up.
