Now that is an example of a genuinely ignorant comment. It's clear you don't actually know what the military in this country at least actually do nor how they train or even recruit. There's also countries that still have conscription.
Unbridled aggression in the military is considered a very bad thing, empath is considered a good thing. You can't have soldiers rampaging around like football hooligans, you need empathy to be able to lead effectively as well as understand the enemy.
The days are long gone when soldiers lined up in a row opposite a row of enemy soldiers and when someone shouted 'charge' they went at it. Often now the military are used as peacekeepers to keep apart warring sides, actual warfare is also very different now when our enemies use innocents as shields.
