Scott pretty much is the villain in this event. Not due to actions perse, but because as others have explained already due to his philosophical stance and unwillingness to budge on Hope. He has become a desperate man leading a desperate people. Remember that teaser image Marvel release almost a year ago now of him wearing Magneto's costume? That turned out to be very symbolic and more true than any of us would suspected as Erik himself asked Scott in the first issue "You sound like I me Scott".
I have yet to read the issue, but interested to know that the X-Men roster roll call in the front has now expanded to include all of Scott's team on Utopia, and has Logan and Storm in the middle. I suspect with Jason Aaron writing this issue that it will be better than the opener.
