The bigger picture here is when the soldier is is drugged up (not of sound mind) full blown possession of an evil spirit a demon who loves bloodshed can happen,
It's no longer the soldier who is fighting but the demon.
The soldier is no longer indespensable.
The true war is satan and his army of what he calls angels are having there pleasure and games.
Whilst the un suspecting soldier doesn't know the real reason the leaders of the world drugged them up.
