Re: Modern Military and Morality
Terrible people are needed to achieve terrible ends (such as winning a war). Man is generally good and resistant to the idea of killing someone else (obviously there are a minority of individuals in society who are murderously inclined).
To make a man kill another man, there are psychological hurdles to overcome, to make you hate your enemy enough to kill. Often religion can provide such motivation, through promising that it is virtuous to kill the other.
For a more secular society, or where you are expecting your soldiers to need to kill soldiers of the same religion, alternatives are needed. Modern military training has evolved to break down the moral barriers and replace them with an instinct to follow orders.
Morality is generally considered to be the responsibility of officers, who are the minority in any military force.
