I have a question: Why people keep saying that Morrisson hated Jean Grey?
I remember the run and I didn't find her unlikable, her problematics where well defined. She was at the same time dealing with a surge in powers that she tried to control (this time better than the first) and was powerless to keep her husband from drifting to Emma's arms.
So, Okay he killed her but since the Phoenix was back we knew she was going to die anyway.
