Blow up those damn normies?
That's quite a great motivation right there...I wonder what happened on the last panel though.
They blew themselves up? Or...Did the spell also group them in with "normies" since they had sex, or something like that.
I thought that last panel was a comical showing of him killing the guys (like when in an anime someone makes his attack and half the building explodes, throwing out the enemy in the proces)
