Was Jada wrong for turning her back on Slim when the girls turned on her?

I mean, Slim did say shady stuff about Jada behind her back but everybody had something slick to say about everyone.

The truth was, the girls were jealous of Slim because she was pretty, skinny and she came from a wealthy family, and deep down, they thought Slim looked down at them. Everybody thought Slim was on BGC because she couldn't get in on ANTM. And a lot of the ANTM girls were badder than Slim who didn't do anything on BGC besides cry, hide in the corner, run her mouth and try to act gangsta with the one girl she knew she could fight (Dalila).

That said, the one thing that pissed me off about Jada was she and Slim made amends before the reunion but at the reunion, Jada suddenly started to yell at Slim and be nasty to her because everybody was attacking Slim so Jada joined the pack. I found that cowardly on her part.
