Certainly it is natural to judge others. And it is good to judge others, because in judging others, we learn what not to do.

Whatever when it comes to our ethics, just keep those judgments in your own mind. Don’t vocalize them to any other human being.

Also as an ethical experiment, maybe try to spend the full year of not talking about others, at all, whether good or bad. Also , don’t quote others, just say what you believe in.
