Woah! god damn, this is a lot more satisfying then it just being that goofy bowlcut kid. Especially since... yeah as kate says, his reasoning isn't wrong. He's been made a part of a terrible machine. And he isn't to know that the Star Bearers (and he himself) were okay doing these things because of the systemic brainwashing.
It's not Barbara's fault she got put in this position. It's not her fault she decided she could only protect the star bearers. But people still got hurt. And at this phase, thoughts like 'the fault is the system we're in' aren't going to come first...
