I think that Blackwatch Retribution cutscene opening tell a lot about their characters at that phase.

While McCree is between surprised and angry at Reyes for shooting Antonio because he never acted differently for what their initial plan was before (at least, he didn’t do anything to put the entire team in danger), Reyes clearly wanted revenge for what happened at their headquarters and he knew he couldn’t do anything else in the situation Antonio presented him. He probably thought Antonio would attack them inmediately after being released, and Reyes swore to not let that happen again and not let anyone else die. Of course he knew McCree would react that way, and that is why he doesn’t confront him back. He understands why Jesse is disappointed on him, after all.

The fact that only McCree reacted that way is because Genji just follows orders. He is not interested in if what they are doing is morally right or wrong and is not surprised for assassinate the target they were supossed to capture. He accepts he is their living weapon and that is why he seems to be prepared to kill the instant the alarm goes off. And what to say about Moira?? She is morally gray since ever. She already does anything in the name of science and she seems to be more interested in the new plan Reyes decides to follow.
