Something that would please me in the most evil and sadistic sense, and yet fill me with revulsive horror that'd make me commit suicide, is to kidnap a young girl, somehow age her body into that of a young woman, rape her painfully and then brutally kill her.
I'd have the most sick twisted fun there is at the time...and then I wouldn't be able to live with myself. I'd go to a pit so dark within myself, I'd visit Hell for R&R.
Or have I misinterpretted the question?
