The herman caine thing is specifically because of an asshole Republican who told people not to mask up, mocked people who did mask up and social distance, and then got COVID-19 from going to a Republican event packed with other anti-mask people who got COVID-19. If you don't think that's ripe ground for schadenfreude, then you skipped past some fundamental concepts of human socialization, tragedy, and comedy.

You can want people to change and then give them shit for changing after they have exhausted all other options. Trump could decide to be a decent human being tomorrow, that wouldn't give him a shield from mockery though. If you only do the right thing because people are nice to you, you're not a very good person.
