Is unnecessary violence against horrible people ever ok?
​
Is it ever okay to provide a violent response to any person regardless of their actions, if said violence would not stop any future actions outside of their death. I'm wording it weird but basically is violence for violence sake ever okay when done towards bad people?
An example of what I mean. You are placed in a room with Jeffery Dahmer. You are fully aware and certain that when you leave the room he will cease to exist again. Nothing you do to him will be held against you, but nothing you do will change anything that has been or will be done. The only thing that will remain after this experience is your memory of the event. Is it morally acceptable or even morally expected to do harm to him in this scenario?
