It's Jason Wyngarde (Mastermind), Emma, the Phoenix Force itself, and then Jean's own human weaknesses, in basically that order. Maybe some of the strongest-willed characters in fiction, like a Batman or Logan or the Gray Lensman, could have resisted the mental manipulation JeanPhoenix was subjected to over the course of that storyline, maybe not - every normal human being does have and should be portrayed as having a dark side to be unleashed, though. To be to some degree corruptible is not an indicator of having always been evil, it's an indicator of being human.
