Ha! Quite right about the banking reference. I did not mean to say the Templar's specifically, but rather men on the ground fighting for a cause. From the modern day to the minutemen at Lexington and Concord to Grog the cave man with club in hand. All have a common lineage in that they are men, with their weapons, fighting for whatever cause at hand and the men at their left and right.

As to morality, well that depends on your point of view. It looks very different from the trenches.
You must remember that before all other concerns the driving force is mission accomplishment.
I believe your operating from a standpoint that is is immoral to kill, and to be good at it. In reality for some its just a job description. A rifleman that cant kill the enemy is as useful as a warm bucket of spit. We need the medic to tend wounds, and the supply clerk to get us beans and bullets. We also need them to be motivated and driven to do their job to the utter best of their abilities else others down the line will suffer. For the grunt that means being a highly motivated soldier dedicated to accomplishing the mission, and his mission is... "The Infantry closes with the enemy by means of fire and maneuver in order to destroy or capture him or to repel his assault by fire, close combat, and counterattack."
There is nothing nice about this, and nor is there anything immoral.

Just remember that nothing is absolute, including morality.
For that matter as a squad leader it would be immoral of me to take a soldier into combat that wasn't highly motivated, dedicated, and hard as wood pecker lips willing to do what he had to to accomplish the mission.

EDIT 2: Furthermore...lol...that's the reason behind the lineage, and the history, and the patches and the chest pounding. Its just flat motivation. We compare ourselves to those that went before us and try to live up to the standard they set. For us it was the 11B's in Vietnam, for them it was the grunts at Chosin and Omaha Beach, for them the men at the Marne, etc etc all the way back to those valiant crusaders, who did what they had to do fir their god, King and Country.
