Two sides can be against each other without either of them being wrong. MC's worries and fears are valid and he can have a say in something that's gonna be done /for him/. He has the right to voice his opinion on this matter. That doesn't mean the Mugos don't have a say in their own life. Or that their opinion is wrong. Both are completely valid. You don't have to disagree with one to agree with the other.

someone please get his mouth to shut up, I luv the uke but he doesn't have any right to say that since he ain't the one who experience it, and especially if it was for him
