Thanks!

There is nothing to add to your article and I just pick up the point with 'Aggression as an instinct'.

Mostly, Aggression is driven by bad intend, either directed specifically against somebody or rather blindly out of overall discontent with the world. But as you propose with instinct, Aggression doesn't necessarily have to be rooted in bad Intention. Martial Arts' goal is to execute physical violence as a means of last-resort Self-defense yet without any sense of bad Intend within. So we basically execute Aggression yet without harbouring negativity towards the receiver of it.

That is a bit off your specific post but it just popped up in my mind to show an example where Aggression is devoid of inner emotional turmoil!
