None of sonic rivals have the same reason to hate sonic.
Metal sonic hates him because he really thinks he's the real sonic, his motivation is to prove he's the "real one" beating his knock off
Scourge hates sonic because being an alternate dimension sonic, he started to feel like an inferior version of him when he noticed sonic comes from the prime earth. Is more about his sense of inferiority and low selfesteem.
Shadow reasons to hate sonic when he was a villain was more about sonic getting in the way of his plans and how puzzled he was when he showed how powerful and fast he was as a natural being, compared to him, an artificial ultimate lifeform, he was even surprised to know sonic looked like him for some reason.
Surge hates sonic because even with amnesia, she knows the reason she became what she is now, is for sonic existing, how she's a knock off and how sonic morals and ethics are stupid in the grand scheme of things, she was too brainwashed and programed to hate him by Dr starline, in the end she just don't want to feel like misfit or a villian, she just knows she was programmed to be like that.
Jet is the more normal rival, by the fact he just wants to prove he's the actual fastest thing alive instead of sonic, while having a high ego.
Knuckles was more about being played for a fool by eggman when his main objective was always protecting the angel island.

All of them are different from sonic despite a lot of them looking like him.
