Considering the fact I'm not a sadist, I wouldn't want to torture anyone, period. Not even if I could get away with it.
I'm a fairly simple guy who just wants to solve problems, not punish others. A free murder would be, Kim Jon ill, Putin, some along those routes.
Evil dictators. Save millions of lives.
The Ill family is a little harder to kill off with a single assassination but Putin is a single guy so, that might be easier to deal with. Maybe Assad.
