I don't think it's quite like that, since there's no direct action aiming to antagonize poor North Korean citizens; they are suffering indirectly due to the harm done to the actual target. In the homeless analogy, maybe the attempted-robber's friends go hungry, since he usually uses the bicycle to go to the grocery store. To me, I don't imagine this changes the calculus much, since almost any intervention will have side-effects.
