What he did initially was, if compared to our reality, akin to allowing terrorists to acquire a nuclear bomb. While he didn't do it intentionally but do to his incompetence, it's a sad fact that he was in a position of power and leadership that allowed him to do it easily, so he bears full responsibility. Then, later, he ruined an official operation to stop the mobile armour, or comparatively, he basically saved the terrorists carrying the nuclear bomb from govenment troops that were about to try to get it back safely. If his motives were questioned later, all he could say would be: "I didn't want that other officer to get any credit." That's exactly what he would say, as well, because he's a blistering idiot.
