Those aren't necessarily opposites.
Some people voluntarily become agents based on greed; others let themselves be used as such because they're stupid enough to do so. In practice, they are agents too, albeit perhaps unwitting ones. The phenomenon didn't begin with Putin; the name "useful idiot" goes back to at least Lenin or Trotsky or some such. The phenomenon itself... I'm betting Julius Caesar was familiar with the idea. And probably Hammurabi too.
