Aggression is not just the shock of the neighbor’s son, the stuffing of socks in the boots of the passers and hats on the head of the actors in the film.
Aggression is first and foremost the protection of its offspring, the production of food for this offspring, the competition between the species.

Ah yes, aggression is not just a property of males. Try to offend the child with the mother.

I dropped it all into a bunch. A vivid example is that aggression attempts to compensate for a lack of mind.
