I prefer it when difficult decisions are portrayed as just that. The wrath of judgment and the concept that a life for a life is justice leave me cold if tehy are portrayed (sometimes literally) in a vacuum.
The worst, most hilarious example I've ever seen was in the Rookie when Clint Eastwood catches a criminal and, instead of cuffing him and arresting him, in front of multiple witnesses at an airport, he puts a gun in the guy's mouth and shoots him in the head with a bullet that has his name carved on it.
In the next scene, he gets promoted.
Hmmm - sounds familiar...
