Would you?

So you care more about the fact that you're likely to get your ass whooped than you do about the fact that you're sleeping with a dude's wife while he's off fighting for YOUR freedom?

I'd say it would be a douchebag move, but his girl is more at fault than anyone else in the entire situation. His occupation has not a thing to do with it. I would feel equally as bad if the dude was a cop, or a firefighter, worked for the IRS, was a veternairian/doctor, anything of the such if they were out of town or on leave for any reason.
