I'm here to tell u why war and aggression, unfortunately wil
stay
If every human thinks like that as wat u said, it will be going
against human's natural born instinct which existed from the very
first day when u born as a baby. War is a result of fighting over
resources, whether was it to protect or to take other people's
possessions.
The aggression in whether to defend or to attack lies in the
instinct for survival. This is true for animals, the ability to
secure resources determine the survival of the entire group of
people or animals. In nature this is wat they called as the
"Survival of the fittest" If u're strong, u conquer, u live, if
u're weak, nature will ensure that u will be destroyed.
Let's put an analogy, if in a far distant future, a massive famine
broke out, and ur home contains the few remaining rations of food
needed by ur family to survive, will u welcome outsiders with open
arms to invade ur home and steal ur last remaining food?
Or let say every humans thinks, as u said, violence and aggression
is NOT okay and they avoid competition with other groups of human
over resources, staying in one area until the resources there is
depleted, refusing to move to other area (already occupied by other
groups of people for the same reason) eventually becos no groups of
people want to wage aggression to conquer other people's resources
for survival, they will slowly die of starvations, thirst....etc.
This will mean the extinction of the enitre human race.
A Utopian world unfortunately, as long as any life exists in this
world, the day will never come. While we can't stop it, the most we
can do is the limit the sufferings of war
