zinger seems to suggest its the opposite, and that storm became a supervillain because he was bullied into desperation or somesuch, which reflects storm's recent account of events. I can't imagine that'll be a hard and fast rule for supervillains though, and I'm guessing leaving everyone with a potential supervillain origin alone is a mistake. Storm did not claim that going broke would turn him into electro and effectively claimed the opposite iirc (i think he said he would lose if he ended the game poor, would become self if he became rich enough and would beocme electro purely by chance eventually if he kept taking actions).
CL has implies he already has the jungle potion, and so preusmably he could became kraven at any time simply by drinking it. Arresting or blocking him could accomplish that, or it could put him into a corner where he feels inclined to drink it. As town one of our principle motivations right now should be to prevent supervillains from being created but it seems to me that its hard to tell whether inaction or action would be more effective in accomplishing that, and so we're kind of in a strategic limbo, at least from my perspective.
