the one that before that happened he turned from not using his powers for personal gain to stealing from a store to get money for his mothers medicine... which is the point he would of turned into a "Villain" because he used his powers for bad, even though it was good cause. The point your talking about was after the fact that he was already doing bad things. In fact, you could add the portion when he killed the other kid by making him fly into the thunder storm. There are numerous points prior to what his father did that he was already turning evil. He turned evil to try and save his mother and when she died he had no more reason to stay good... which kind of reminds me of Star Wars when Darth Vader is born because he thinks he killed Padema and has nothing good to live for anymore.
