I told Mr. Fury that there was no way Wolverine would kill Jean. He loves her too much. And even though the world would be in trouble with Phoenix, he still wouldn't be able to do it.
It escalated to:
Him: No way. Wolverine would definitely do it! He has a responsibility to the team. Cyclops on the other hand, he wouldn't be able to do it. They're in love and that would be too hard for him.
Me: *Snort* Come on, Cyclops so would. He has that whole 'I'm a leader, that has to make me cool!' thing going on. He'd kill her for the betterment of humankind and all that junk. Now Wolverine, he couldn't do it. He's like Spike in the second episode of season six where he mentions that the group didn't tell him they were resurrecting Buffy because even if she came back wrong, Spike wouldn't allow her to be destroyed. There's no way he could hurt Jean.
... And it went on and on and on from there. So, he told me I should make a poll. And since I have a couple minutes to breathe, I give you one! An X-Men poll! You people seem to love those!
In X-Men 3, who is more likely to kill Jean if she were to ask them to when she goes all Phoenix on the group?
