Woah, a "evil" Gohan. Though if he's still following them, it'd be because he's still weaker. Well, obliterating weaklings isn't going to allow him to get stronger. I wonder what'll happen once on Earth. Even if Piccolo died, I would expect them to go to planet Namek and revive Goku and Piccolo who must have trained and gotten stronger, simply because Poppo would know and trigger that quest once Kami is gone. Then again, the story is "The last Son".
