Could be part of a package of DLC for all the squad mates post suicide mission, as to Kolyat while he's not a killer I'd say that he'd be willing to take his fathers place on the team... admittedly why Shepard would want him is questionable but it makes more sense then just killing him off as a plot decision or having a miracle cure.
