Corrupted changes something from a base state to a worse state. Redeemed returns something from the worse state to the base state. I'm looking for a word describing a change from the base state to a better state, without implying a previous fall.
"Capone corrupted Chicago. Giuliani _____ New York." (well, depending on your politics.)
"Alice corrupted Bob, leading him into a life of vice."
"Claire ____ Dennis, leading him to a life of virtue."
Thesaurus has not been helpful, as it gives antonyms for corrupt the adjective, but not the verb. Lexipedia was similarly unhelpful.
