Was PhiPhi's anger justified?

(Before you say, yes i know it is heavily edited and all of that)

So i've been rewatching season 4 recently and whilst the show has edited certain people to be villains, queens like roxxxy seemed to have been hating/arguing with jinkx for no valid reason. whilst i think phiphi attacking willam was not justified, the arguments she had with sharon seemed to be for a reason, with both times sharon throwing phiphi under the bus for no apparent reason.

again, i know it's edited i'm just curious to see everyones opinions on phiphi in the context of the show.
