Once you're in the place of yes, I want this madman to go hurt people I don't like, there's no drawing a line at 'but he better do it rationally and predictably.' They never think the leopard will eat their face of course, but they're not picky about who else's it eats. Who is almost immaterial.

when the leopard finally comes around to eat their face they will say with orgiastic glee "yes! eat my face, daddy! i give myself to your sublime retribution"
