I disagree. Many uses of mind control are unquestionably evil. However, there are applications that are not (or at least no more so than other applications of force).
Take the classic scene from Star Wars, "These are not the droids you are looking for. Move along". Was this a moral act on Obi Wan's part? Possibly not. Was it more moral than whipping out his light saber, cleaving the storm troopers in two, and potentially endangering nearby innocents? IMO, unquestionably. Was it evil? No, I don't believe it was.
Similarly, using charm to steal from a shopkeep is evil. Using charm to stop an orc from killing a child is, IMO, a very morally safe position. It is certainly no less moral than if you tried to stop the orc using violence, and arguably more moral than violent means.
