| > Not necessarily.. There are preventive methods such as the death penalty or deep, permanent incarceration with no sunlight to prevent killers from continuing to kill. |
They'd get out again. They always do, whether through their own volition or from someone else.
>Batman or the police could also have decided to take the law in their hands and kill those villains themselves or look the other way when these villains are in trouble. I can't count how many times Batman even risked his life to save the Joker's life. That is ridiculous.
Batman isn't a killer and though part of him wants to see the Joker dead, he cannot bring himself to do it or to really let it happen. While this wasn't true in the beginning, it has become more so. Blame Thomas Wayne for instilling the value of all human life, into Bruce as a boy. This is why he will not kill. If he were to do so, he'd disgrace his father's memory and thus his time as Batman would end. And while the police would probably love to do it, none of them will go that far. Not even Jim Gordon himself.
| > I don't think a villain has to be a psychotic killer to be interesting. He or she can be interesting without being a killer. I find that Marvel Comics villains in the days that Stan Lee was writing interesting and fun without them being bloodthirsty. Not even Doctor Doom, Marvel's premier villain, went around killing people left and right when Stan Lee was writing him and yet he was a fan favourite.|
Doom prides himself on being honorable. The Joker doesn't. Besides, Doom has no problem killing. His failing is his insanity doesn't make him as off kilter as the Joker. The Joker views life as a joke and could care less if someone lives or die. So long as he can have his punchline and get under Batman's skin, that's all that matters. Life has no meaning to him, while it does for Doom.
| > I am not saying that killers should not be used in comics, just that they should not be recurring characters because I think it would be a miscarriage of justice to the victims in letting them live to potentially continue their work.|
That's what makes the ones like the Joker both loved and hated. He mocks the judicial system and the people who want him to be punished. He is chaos and anarky. The punchline of life. Besides, no matter what happens, whether he lives or dies, it still won't change that the lives are lost. In real life, justice is not always served. The criminal goes free or is never found.
