The inclination to aggression is how nature uses man's asocial sociability to lead mankind from barbarism to culture, i.e., to force mankind out of its lazy existence to produce civilization (Kant's 4th proposition in his Idea for a Universal History: also expressed by Turgot, Vico, and Smith).
See also Hobbes' Leviathan (Ch. XIII), Nietzsche's Genealogy of Morals (Second Essay), and, of course, ch. 5 of Freud's Civilization and Its Discontents:
"Men are not gentle creatures, who want to be loved, who at the most can defend themselves if they are attacked; they are, on the contrary, creatures among whose instinctual endowments is to be reckoned a powerful share of aggressiveness. As a result, their neighbor is for them not only a potential helper or sexual object, but also someone who tempts them to satisfy their aggressiveness on him, to exploit his capacity for work without compensation, to use him sexually without his consent, to seize his possessions, to humiliate him, to cause him pain, to torture and to kill him. Homo homini lupus [man is a wolf to man]. Who in the face of all his experience of life and of history, will have the courage to dispute this assertion? As a rule this cruel aggressiveness waits for some provocation or puts itself at the service of some other purpose, whose goal might also have been reached by milder measures. The existence of this inclination to aggression, which we can detect in ourselves and justly assume to be present in others, is the factor which disturbs our relations with our neighbor and which forces civilization into such a high expenditure [of energy]. In consequence of this primary mutual hostility of human beings, civilized society is perpetually threatened with disintegration."
The world is inhospitable and you're not a special snowflake. You want advice, seek the wisdom of Silenus.
A pleasant evening to all.
