Kazui is more of a wild card than Mikoto at this point. I don't think Mikoto would ever help Kotoko because he's not violently insane, he just has his priority of keeping himself safe. Due to that I think he would only see Kotoko as a threat and would always suspect her of betraying him in any deal she offers.
Kazui meanwhile doesn't really do what people think or he even says he would. He says he wants to prevent violence from happening to the prisoners in Milgram, and even told Kotoko this, but his cell was next to Mahiru's, and he apparently didn't do anything to stop Kotoko from beating her while he helped Fuuta. Even Jackalope pointed out how weird it was. Then Amane was somehow able to kill off Shidou even though Kazui is also right next to her cell and could've kept an eye on her. Feels like there's something off with him entirely.
