Doctors, nurses, and their community fight against a thing, and fight bravely, risking their sanity in resisting actions of forces whose root causes they could not directly address. Soldiers and their community fight against people, leaving the actions of their enemies to others, but able to seek them out and fight directly against their foe, even eliminating them if they were lucky. One side had absolute purity of purpose but lacked satisfaction. The other could attain the satisfaction of destroying the enemy, but only at the cost of becoming too much like what they struggled against. Warrior and healer, parallel wars, similarity of purpose, but so different in their actions. Diseases of the body, and diseases of humanity itself. Wasn’t that an interesting way to look at it?
