What some of you may be missing is the intense pressure put on these military people by the witness mother constantly telling them that what they are doing in the military is anti-god and essentially that they are murderers. Look at the pilot - his mother had him so brainwashed that she successfully prevented him from even wearing his military uniform when he was around her.
If you combine that with a mind that is not totally freed from the cult, and may have some self-esteem issues - what you have is essentially gasoline and matches in the hands of what is emotionally still a little kid.
