Just because Jean said something doesn't mean she should have telekinetically killed them all. Storm IS right: any of Madrox's dupes are a real person in and of themselves. Jean under Coleite has become more of a battlefield leader, and so her words reflect that role: Storm did something, so either Jean can let her freak out, or Jean can try and calm her down. If Jean had TOLD Storm to do it and not done it, that would have been hypocritical. As it stands, it was attempting to calm a freaking-out teammate.
As far as Iceman goes, well, whatever. It's not gross mischaracterization, because Ultimate Iceman has never been a genius with his powers under any writer. It doesn't even count as a missed attempt, because it doesn't really matter.
