[Batman] We can talk about the philosophical reasons why Batman doesn’t kill the Joker, but why has the Joker never been legally executed?

With all the crimes he’s committed, there’s no way a mental illness defense would still exonerate him. Besides, it’s not like a trial is really necessary, the man himself glories in his crimes. Certainly Batman would be at least indifferent to this option, as he’s discharged his duty by bringing Joker in. Now it’s up to the law to decide what to do with him. So why hasn’t the law decided to execute him? Why do they keep trying to send him to Arkham, where they know he’ll just escape again?

Fuck that, why hasn't he been illegally executed? No cop or guard ever decided to just shoot him and claim self defense? It's not like any jury out there would ever convict considering how many deaths are on the Joker's hands.
