Unironically it is his fault. Joker's got multiple issues where he says he only breaks out of prison to fuck with Batman lmao
Even without killing him, Batman could
>cripple Joker
>stop being Batman
>use his influence as basically the richest cunt in-universe to force judicial changes
>help create tech that actually could contain Joker
>just put him on meds
Instead he just puts him in the basic bitch prison system that literally every breaks out of every couple weeks when they get bored while doing nothing about it until another couple families die
