Is it possible to enjoy war? ... To be pro-war? Pro-death?
"War is t3h w1n! I <3 D&D!"
Unless you've been killing and judo chopping since birth, hardened beyond belief, and have lost any and all semblence to humanity or human beings, then I would expect the answer to be a simple no.
If this particular Sgt refuses to deploy, then fine, let him face the consequences of his decision. He volunteered for this.
But to insult or degrade someone for not not enjoying, not being pro-war, pro-death, is sick. Soldiers follow orders - whether they enjoy it, or are for, or against it, is beside the point.
