Re: If the author wanted a "killing is always wrong" shpiel, he picked the wrong villains.
"I don't care what excuses are given, the Joker gets out and kills again, time after time after time."
The Batfamily aren't judge, jury and executioner. Gotham has enough judges, juries and executioners of its own -- it's their job to decide if Joker ought be executed or not.
