At that, not only there's not a justice system, as there isn't an "expel from colony" option. That way, if someone fights like that, or, let's say, some pyromaniac decides going on a fire starting spree right into your devilstrand farm or the colony food suplies (real story), not only you can't punish him, as also if he dies the rest of the colony still goes "oh, poor him. We liked him so much. Remember that time he put fire to our food stocks and we spent winter eating taht awfull berries, eventually leading to other three colonists starving to death? Oh man, that was a good prank".
Maybe the other colonists should at least have a stronger opinion about theese things (like, everyone should have a social negative opinion about someone who started a fight, with a special weight when it happens to someone they like) and also have some option for punishment (as said, maybe we could select one of such social interactions for a reason to go to prison for a day, and the other colonists could get a mood boost/penalty if they agreed or not with it) and for expelling (same thing for mood effect on rest of people, maybe the expelled colonist could randomly join a pirate band and cause future trouble XD).
