She's grieving and they obviously won't turn on her but Rogue was destroying military bases and "rampaging across the country" as Cap put it. On top of that she killed a person on foreign soil. Her lashing out is understandable considering what she just went through but still these actions don't exactly sell a nice image of mutants to humanity. Cyclops and even Beast seem to be over being model citizens just to be accepted as human beings but I don't think the same goes for Kurt and Morph.
