Raubahn cutting down a resistance member is probably not because they're tempered. Why would he issue them a challenge/threat if he was just going to kill them? Most likely they're fighting because of some other disagreement.

As for Lolorito, it's simple enough to assume that the Scions are mediating a truce between him and Nanamo. Not the most satisfying answer, but the simplest one has, more often than not, been the correct one in FF XIV.
