If your friend got into a fight with 2 grls that u didnt kno.. are u supposed to help her?

hmm mah friend got into a fight wit 2 grls that i did not kno.. i kept tryin to stop it by pushin tha grls away and pullin mah friend bak.. but i didnt hit any of dem and none of dem hit me. So at first i let mah friend fight one of da grls because dey had beef anyways. But then afta a while, one of tha grl's friend jumped in and started hittin mah friend frum tha bak and thas when i ran in and pushed dem offa her and tol dem to stop it fo real. and den dey left. I think it was real unfair.. cus i didnt kno wat to do cus i aint neva seen anythang like dat. But i was mad that i didnt jump in and fight fo her... da bois all felt bad cus dey didnt do nuffin and knew it was wrong dat it was 2 vs 1. but i dunno.. was i supposed to help her?
