But there's too much against the theory. With Garnet I admit, there was plenty of evidence. What is the likelyhood, anyway, that she just 'forgot' she was a fusion and randomly just ended up hating them

I believe Jasper takes pride in her superior strength that would match that of a fusion, and she looks down on anything weak because of this. She thinks fusions to be an excuse, like a poor little attempt to try to win once you're already losing. Since she can win on her own, she scorns those who team up to defeat the opposing side.
