From CNN:

\Lt. Gen. James Mattis, who commanded Marine expeditions in Afghanistan and Iraq, made the comments Tuesday during a panel discussion in San Diego, California.

“Actually it’s quite fun to fight them, you know. It’s a hell of a hoot,” Mattis said, prompting laughter from some military members in the audience. “It’s fun to shoot some people. I’ll be right up there with you. I like brawling.”\

I have nothing but respect for those who serve in the military out of a sense of duty or honor or patriotism. I may not agree with their decisions, but I respect and honor them for living their convictions. Having said that, I think there is a name for people who “think it’s a hell of a hoot” to shoot people.

We call them psychopaths.
