"He should have just like controlled himself," Kim says in new "Keeping Up with the Kardashians" clip.
In a new clip from Sunday's "Keeping Up With the Kardashians," Khloe calls the whole ordeal "super frustrating" and Kim says she "went off on Rob" in family group text messages.
"Did you see how I just like went off on Rob in our group text? I couldn't take it," Kim said.
"Listen, there's a plus and a minus," Khloe said. "One of the plus of all this -- there's no way Rob and Chyna could get back together after this, right? Let's focus on the positive. The negative is all of this other shit right now."
Kim continued to express her disappointment with her brother for posting nude photos of his ex-finacé during that infamous social media war.
"He should have just like controlled himself," Kim said.
"So Rob and Chyna have officially broken up, but they obviously still have to communicate for the custody of Dream," Khloe said in a confessional interview. "They're still having a hard time getting along. The legal battle that has been going on between the two of them has been super frustrating. I feel like this is escalating to a place that none of us could have ever imagined."
"But it just sucks, like he's made out to be this bad guy when she's taunting him," Khloe told Kim. "Like, love makes you do f-cked up things. You think anyone's proud of that? No. You don't f-ck with someone's heart and emotions."
