Okay this is a very earnest examination of a little joke I was making but I will say that I agree, it's just that kids at like 5 simply can't really conceive of a "social contract" for the most part

There are some cool chimp studies though that showcase how infant humans and infant chimps, when presented with a little "play" involving a shape atop a hill that pushes another shape down whenever it climbs up, have very different priorities. When presented with physical toys that match the shapes from the play, infant humans usually chose the shape that was getting pushed down, while the infant chimps chose the "dominant" shape

It's not super conclusive tbh but it's cute that kids seemingly want to console the bullied actor
