Does not one who enlists in the military demonstrate his disregard for
his own life and those whom he intends to kill?

No. That's the perspective of a civilian who's never served, and thus
has no idea who the (U.S.) military is really composed of. They're
just ordinary people, and no, they have no desire to kill anyone, or to
die themselves, any more than someone who gets a driver's license
demonstrates such thoughts.

Those who enlist demonstrate their willingness to suffer hardship in
return for the greater good. This could be a desire to do something
good for themselves, their country, and/or the world in general.
