Greetings. There are two kinds of persons in our military. There are the brave, dedicated warriors who fight for their country and receive no pleasure in taking people's lives when necessary. They make up the overwhelming majority of our armed forces.
Then there's the other kind -- like three-star Marine Lt. General James Mattis, who was recorded at a panel discussion saying, "It's fun to shoot some people!" and "I like brawling!"
Regardless of the circumstances, anybody who gets enjoyment out of killing other human beings -- even the most vicious of enemies -- is unfit to wear the uniform of the U.S. military, and probably is in need of serious psychological help as well.
