To be fair who hasn't tried to murder the Hulk at this point.

Hell, at the point they were slut shaming her over this, Jen had been depowered by Tony's super hero suppresion nanites because she attacked him after finding out he and the Illuminati had shot Bruce into space, but that clearly didn't stop her from working with him later.

Besides, Juggernaut was a good guy at this point (I think? I know he was a good guy for a while).
