I love this question! It’s so interesting to see where everyone else comes from and the conclusions they reach.
It’s a tough one because, in my mind, it’s hard to draw the line on just how mentally competent the Joker is. I’ve always seen him as someone who certainly has a cocktail of mental health conditions, but he also openly lies to himself and others about what is symptoms are. He also uses them to gain pity and support, as he did with Harley Quinn, while downplaying his abusive and cruel tendencies.
Which makes me a little unwilling to say he shouldn’t be killed because he’s mentally ill. He might be, true, but he’s also in control.
Again, that’s just my take there.
But I also feel that Batman shouldn’t be a system. He’s someone who is trying to fix Gotham because Gotham is broken. It needs a competent criminal justice system. One that’s able to judge and issue appropriate punishments. Batman killing the Joker would break any hope for that because it’d split an already weak system down the middle. Those who are Batman loyalists who believe he was saving lives vs those who believe a masked vigilante killing escaped convicts is just too far.
Let’s keep this subject going, guys! Do you agree or disagree here?
