How is John Proctor from "The Crucible" and Jay Gatsby from "The Great Gatsby" alike? Different?

Wow, the context is so different. Still I suppose both these guys go against the culture of the time. Gatsby goes against the filthy rich status-quo about old money, entitlement and inheritance. Proctor goes against the established theocracy of the time. Both are counter culture rebellious in their own ways. THey are different in that Proctor is much more aware of his limitations and frailties. I don't think Gatsby ever becomes that self aware of his own obsessive shortcomings.
