so I made two similar artist-type characters with this advice. Which one do you like better?
Gustave is a world famous chef. He goes to Rapture in hopes of finding a culture that would better appreciate and understand his work. He grows bored using the same tired ingredients again and again and begins "experimenting". The amount of patrons at his restaurant dwindles as his food grows more and more disgusting. Gustave, desperate for attention, begins kidnapping ponies and forcing them to eat his deadly concoctions, claiming that he's "just trying to show them true art."

Gustave is a famous comedian but critics claim his humor is to "crude" (Remember, this is the 1940's). He moves to Rapture in hopes of finding people who will appreciate his comedy. His prediction proves correct and he opens a very popular comedy club in Rapture. When the civil war hits, though, no one shows up for his performances anymore. Gustave begins kidnapping ponies and forcing them to listen to his jokes. Those who don't "get" his jokes (they stopped making sense at this point) are killed in comedic ways (i.e. crushed by dropped piano, blown up in a shower of fireworks, etc.)
