When people think of LIIs, they don't think of them as being evil. I beg to differ. Post some LII characters who by virtue of some vice or character flaw, committed unspeakable evil.
Antonio Salieri (F. Murray Abraham may be LII too).
Supervised Mozart (IEE) to his death. I think an often encountered flaw in unhealthy dominants is jealousy of others' accomplishments and ego-centrism.
