Generally, if someone today is upset at a past person for being unethical, it is about an issue that was at least somewhat controversial in that time. People judge Thomas Jefferson for having slaves, but not for not supporting LGBT rights. I think you can do a pretty decent job at figuring out what a future person might judge you for by looking at current debates and how they might evolve. Eating meat is certainly one, as is owning pets. Killing insects could be one. Those others are very unlikely to be since they’re not current issues.
