Interesting take on Karma, though I'm not sure if I'd feel comfortable with it without seeing the full context of the intended scene. It would definitely go against Karma's background in the comics, as she was the first official member of the team and has always tried not to use her power maliciously, unlike her brother (who became associated with the criminal elements of the family, and later turned out to be not quite dead after Karma had seemingly been forced to kill him years earlier).
