Airbubba,
I had already read the interview you refer to, which is what made me think O'Malley would be inherently less likely to be hasty or indeed unforgiving. Given his own experience, I suspect whatever she did must have left him / The Air Force with little choice. Added to which, he wouldnt need much in the imagination department to realise that this would reignite interest in his own past incident, so another reason to believe that he had no choice but to remove her.
