If I was in the same situation in front of a bunch of people where I was under heavy scrutiny, I'd be doing everything in my power to hold back tears like Kyle. Everyone expects men to hold it in and be emotionally in control at all times. While that may be a ideal to try to personally emulate, it is also unrealistic. Even army grunts back when men were tougher can break under scrutiny. I can vaguely recall a video on youtube where a new recruit disobeyed a order (cant recall the reason). The military court was doing everything they could to verbally chastise him and make him think he was either about to be court martialed or worse. When this was happening to the grunt you could see him starting to break down. He went from being rather calm, to agitated, to quivering lips to breakdown. Him disobeying the order for all I know might have been justified but that didn't stop his response. With that in mind I do not find it unreasonable that Kyle would have a hard time holding back tears. Hes a growing adult trying to comes to terms with reality, and sometimes trying to deal with it, is not a pretty sight.
