I do not agree that criticisms of other people represent jealousy. Sometimes, yes, that can be the case, but there are times where there are definitely things other people do that are out right toxic and manipulative and disrespectful to others.

If someone comes to me and tells me they want to pick on someone because they think it is "fun"? My criticisms of a person like that has nothing to do with jealousy. I really dislike people like that, especially when I take the time to tell them "why" they should not pick on that other person and they say "I don't care, I am going to do it anyway". It isn't very often that I really dislike someone. I deeply dislike people who abuse children and animals and my criticisms when it comes to that are no where near jealousy.
