Congratulations anon. You completely missed what this discussion is really about, but let me answer anyway:

No, him having emotions is not a bad thing. But letting himself be controlled by his emotions is. And considering how his personality changed 180° I'm sure we really can blame it all on Ultear.

He deeply loved Erza and risked his life to free her from the torture of someone else and then just a few hours later he was greatly enjoying torturing that very same girl for crying out loud! Does that sound like he was in the least bit of control over himself? Ultear might not have controlled his every move like a Marionette, but she completel re-wrote his personality to the point of there being nothing left of his true self.

And no, I seriously doubt that any FT member would be willing to commit suicide, almost beg Erza to kill them or wait patiently for Millianna to strike him down (which probably would really have happened if not for Ultear and Erza being there) if they went through the same thing.
