Just curious if there are people who don't fight unless forced to

Yes - in fact, there are players who don't fight at all and only try to escape; and there are a few who literally /sit until dead.

or those that defend those being attacked when observed, or is this place all anarchy

People defend guildmates and other friends. If there were a 3-faction encounter, the 3rd faction to enter the fight would probably play opportunistically and either snipe kills, jump on the weaker target, kill whoever they dislike more, or maybe attack the larger force in the hopes of taking whatever NPC they are fighting over (if any).
