Lock him in a deep dark hole forever...
The cane (public), stocks, and reserve the gallows for his next , if any, misdemeanor.
So more people must die before dealing with him appropriately?
The death penalty is an effective deterrent. It GUARANTEES no repeat offenders.
And it's not only about *justice*, which there never really can be because even if he dies, it will not bring back those he killed or heal everyone injured by him.
What it does do it protect society from repeat offenders, and HOPEFULLY, give the next guy something to think about.
