As in "the fruits of the Devil"

For the Worst of Us, the Diagnosis May Be 'Evil'

In an effort to standardize what makes a crime particularly heinous, a group at New York University has been developing what it calls a depravity scale, which rates the horror of an act by the sum of its grim details.

And a prominent personality expert at Columbia University has published a 22-level hierarchy of evil behavior, derived from detailed biographies of more than 500 violent criminals.

He is now working on a book urging the profession not to shrink from thinking in terms of evil when appraising certain offenders, even if the E-word cannot be used as part of an official examination or diagnosis.

I think I'd prefer people keep their moral chocolate out of my clinical peanut butter, but it's an interesting discussion.
