Alternatively, not everyone in the military is a self-obsessed psychopath intent on murdering Manning because he didn't hold to their ridiculous concept of honour.

I am a reservist, I have been mobilised at short notice and served overseas, and amazingly I would have no problem whatsoever not murdering Manning or someone like him, and indeed, were he in my custody, I would have a problem with and would even try to stop some wandering psychopath who did try to murder him. Crazy days.
