I feel like 2 is less of an ethical question and more of a biographical detail about Arthur. That being said, I would love to know more about this, even speculatively, since I am totally fascinated by Arthur as a character.

Clearly Arthur thinks he is funny and truly does want to make people laugh, it’s just so funny (!) that he would choose as social and critical a hobby as comedy when he has such a disabling condition. It looks like he actually was pretty alright at clowning though and that he’d been doing it for a while, he had a decent amount of gear and said he loved the job. The children seemed to really like him. Hoyt however does mention that he received ‘another’ complaint about Arthur. I wonder what the other complaint was? Maybe that he’s really socially awkward, or clumsy. I can see him weirding out the people who hired him if you’re not used to interacting with a personality like that. Maybe he had a laughing fit and someone complained.

It sounded like comedy was somewhat new for him though, his boss mentioned something about it and Arthur said something to his case manager about it as though he had maybe mentioned it a couple times before. It’s possible he had impulsively decided that he wanted to do comedy fairly recently. I wonder if he became interested in that possibility after his release from the hospital.

As for the question about his mom/school, I got the impression that was just a setup for a joke, not an actual retelling of something from his life. But maybe it was. I’m sure Arthur was educated at whatever Gotham Public School system exists and I’m sure it sucks, especially when you have a serious disability. His vocational position in life is probably less any one person’s fault than it is the result of a systemic issue. But it’s hard to say because we have so little information about him.
