[Inglorious Basterds] Why not just kill him?

#Spoilers ahead, obviously

So, at the end of the Movie, the Lt. gives Hans his signature mark. But why? The guy can play it off as (for example) something the Nazis did to him. It's established earlier that the Basterds aren't known outside of the Nazi forces, and even if he met someone who *did* know what it meant, he could still claim that - I don't know - they did it in retaliation.

But beyond that... **why didn't they just shoot the guy**? The only people who know about the deal are Hans, the Lt., an unnamed General and the other american whose name I can't remember. Nobody will ever know, or care, that they betrayed a despised Nazi officer.

Lt. Raine is a career hardcase; "I've been chewed out before". To be a guy like that and have a field command instead of running a kitchen patrol somewhere in the asscrack of Nebraska or bouncing a ball off your cell wall for a decade in Fort Leavenworth, you have to know how far you can push it, where you can take liberties, and where you need to pump the brakes. 

Raine knows he can shoot Landa's henchman, even though a deal was specifically made for that henchman's life; Supreme Headquarters doesn't give a fuck about some random enlisted guy. He also knows he can mutilate Landa, even with the promise of safety; Supreme Headquarters want's a top ranked SD officer who can give them the dirty details, and whether or not he can win a beauty contest is irrelevant. But if Raine shows up with two corpses and no prize then he's going to wind up in 12 gallons of hell, no matter what excuse he cooks up.

I imagine Raine really, **REALLY** wants to make that Nazi wear his balls as a hat. Operation Kino was all but a total party kill for what was left of the Basterds, and leaving that smug asshole not just alive but profiting off the action must have rubbed him quite raw. And since a big part of Landa's reward was being able to fuck off and pretend he was *never really a Nazi* with the Allies backing his claim to be a career-long Allied double agent, no doubt Raine was super keen on getting some kind of retaliation. Thus, he carves his masterpiece...
