Or maybe it's the other way around. I remember a short from the 80s Twilight Zone series where the UN is visited by aliens who say that we were one of several races they created/seeded to see if we had potential. Unfortunately they were bitterly disappointed in our progress and had decided that wiping us out was the only answer.

Desperate, the humans asked for a few days reprieve to prove themselves. When the aliens got back after those few days, the humans proudly showed them how the warring nations had setup peace treaties and agreed to dismantle weaponry.

Unfortunately, the aliens were bitterly disappointed because they were a warlike race and they thought we should have been building disintegrators or out conquering our galactic neighbours by now, so the peace treaties doomed our race to extinction...
