I agree with you that Bae could see how the magic had changed Rumple and not for the better yet I still think he was naive in thinking how everything would be better if Rumple just gave up the power. Whilst Bae certainly wasn’t wrong about how the magic made Rumple worse, I don’t think he was seeing the bigger picture of what the consequences could be once Rumple gave up the power.Had Rumple been treated right by others before he became the dark one then I think he would have been more willing to give up the power once he’d stopped the ogre war.
