That might be a bigger problem than just being in the Commonwealth. If someone went kill crazy and murdered a whole bunch of gang members, the rest of the gang would likely come crashing down on them too quickly to give them a chance to survive.

The only way I can think of swinging it would be if all of the gang were survivors of the same incident in Nuka-World. Possibly a group who were outside of Nukatown USA during their blackouts and who could make up an excuse afterwards as to how they managed to survive while the others in their group were killed.

There might be enough suspicion of their story to cause the group to break off from the main gangs to form their own faction, especially after Colter's assassination broke up the main alliance and had everyone vying for power. This would lead the group to conquer one of the unclaimed zones for themselves, using it as their base while defending themselves against the other splintering factions.

Would the "kill-all" order include other Synths, or would Synths have worked together during the incident to wipe out all other lifeforms?
