Lawyer by day. Rules lawyer by night.
Well not exactly. Kino Loy had been there for a long time and had less than a year left. He doesn't "believe in the system" or in any kind of just world theory so much as he doesn't want Cassian to cause any trouble that would jeopardize his own place in a very cutthroat world. He was going along to get along. And if working his fellow prisoners to death gets him a step closer to his own freedom, he's okay with that.Kino Loy. I mean that was the central story arc of the episode. Kino Loy has represented the hard-nosed tough guy that ultimately believes that if you follow the Empire's rules and work within the system, that eventually it's going to work out - at the end of the program or the process or whatever, there will be a just world. And now that Andor has his respect, because Andor's team is the most productive on the floor, Andor has been working on him this whole episode trying to get him to see that he can't work with the Empire. And Kino Loy has literally been turning his back on Andor. But after the death of "the old guy" and learning that the Empire isn't ever going to let anyone out of the prison converts Kino Loy to Cassian's point of view, signified by the fact that Kino answers Cassian's question about how many guards work each floor. In other words, the room supervisors and other "trusted" prisoners (like the med-techs and other prisoners that work behind the scenes) will now be in on the escape attempt.
That was the point.
He thought that playing his little part in the system would get him out. After all, he'd seen that before. Yes prisoners died but prisoners also got freed (so he thought). But with the purge on Level 2, he realized it was all a snow job and that, at this point, they could be purged at any time for any reason. Meaning that his only hope of getting out alive was to escape as soon as possible.
He's not doing it for justice. He's probably not even doing it for revenge. He's still saving his own skin because this is the only way out.
