Ah! I am glad you chimed in :D
So maybe today violence is a symbol of nostalgia or something philosophical like that
It doesn't explain why little boys, like to crash their toy cars , destroy stuffs and get into fights. While they aren't exactly "blank slate", it's not linked to a nostalgia but more an intrisic mechanism... So it would mean it's already there, in our genes, waiting to express itself.
That is such an interesting thought. Yeah, maybe inherent violence is something akin to a primitive or evolutionary trait linked to survival. Then it becomes more of a biological question as well. But also, doesn’t our society still reward violence in some sense?
