I've never liked Kenya, but have had moments of empathy. I do feel a bit sorry for her. Not that sorry though. We all have problems, and if you see that yours are causing you issues with others, it's time for some self-reflection and perhaps some counseling.
I can believe Porsha attacked Kenya. You could see in the last few episodes when they would argue that Porsha was over it. She had all she could take, I guess. I don't like violence, but I almost can't blame Porsha. Kenya is shady in the extreme. Her motivations are not nice.
