[MARVEL] Would Ghost Riders Penance stare work on Jean Grey?

Didn't she commit genocide as the phoenix?

Technically, Jean did not commit genocide. The Phoenix Force created an exact copy of Jean's body, memories, and personality, and used that as a physical vessel for itself - it hid the real Jean in suspended animation. Jean later gained all the memories of the Phoenix during the time it believed itself to be Jean Grey, so in most ways, the difference is pretty academic - the Phoenix was psychologically identical to Jean, and the now-living Jean has all those memories too, so in most ways they might as well be the same person. 

However, Ghost Rider's Penance Stare affects the soul, not the mind. Jean's soul was not present when that genocide occurred.
