Okay, here's a nice comparison.

Take a Doctor or surgeon for example. These people have to slowly cut open people, crack open sternums and wriggle their fingers and various utensils around in squiggling organs. Often times, people die on their watch, or patients are rolled in who look like they have been put in a blender or something. It takes a certain ability to be impartial, a level calm coldness to be able to do their job, the same as a soldier must.

A soldier must be able to know when to take a life and when to preserve one, and as with soldiers too, people will unexpectedly die, and they will have to live with this. However, you don't see the average soldier or doctor going around chucking live animals around.

Any soldier who cannot deal with these types of things - though harsh they may be- even if they're in their peak physical conditions, they are not fit for war, and should be discharged. Mental instabilities, like the one shown in the video, are only problem causers and never do anybody any good.
