I think it depends on which definition of pedophile you’re using. If you mean the act of abuse, then the fame gave them the opportunity and unless pre crime is wrong they weren’t pedophiles prior to the act so in some sense it did make them a pedo (but obviously they’re still responsible for their own actions). If you mean the mental disorder of being attracted to minors, then it’s likely they always were, I don’t think fame would make you suddenly desire that.
