actually, in my fantasies, it usually did not reach the point of death either, if that person dies you no longer can torture them so it is a great waste.
but when I got into more thinking about everything as usual and if I assume to get into the situation when I could really torture my enemies without consequences, philosophically I cannot even hate them because by hurting me, they actually gave me all that pleasure to hate them. If they were innocent I could not enjoy any of that.
So the only reason to kill someone is if you fear them
but at that time I was also thinking not only about pleasure in torturing my enemy but in eliminating them from existence so that they could not hurt me anymore.
Yes I have seen that Aladin movie quite a long time ago, but that idea is not so simple, because if you harm someone too much they may just commit suicide and that will be pretty much the same as plain murder.
To do perfect torture you must let your victim keep hope all the time and never get into depression when nothing matters anymore. When you reduced that person into a piece of meat torturing it is just as pleasant as tenderizing a piece of ham with a mallet.
