I’d offer you a counterpoint (ignoring the issue with Lutris and AI for a minute):

If you choose not to judge your own actions by the expected consequences of those actions for everyone involved, then how exactly are you supposed to judge them? If you’re following some rule that disagrees with the utilitarian view, then by definition it’s a rule that in your own opinion leads to a worse outcome for everyone.

It’s of course completely fine to not be utilitarian, but trying to claim that all utilitarians are either stupid or evil is just incorrect.
