^Seems reasonable enough to me. At least one of Khan's people (besides himself) went a little loopy during their exile, and presumably they have stronger minds as well as bodies. If their first acts upon achieving freedom hadn't been mired in violence I might have felt sorry for them. At minimum, if they could have been taken alive, I'd hope the Federation might have shown them a hint of leniency (a -hint-) for all the crap they'd gone through.
