Much of violence is "inadvertent".
In a non-violent world, people would be more direct.
People would be living in a "primary" way and enjoying life itself.
That is, they would be doing things for their own sake and not for secondary (far-removed) rewards.
Life would be simplified without the complexities of money and working at jobs.
In the "best of all worlds", it's a win-win, with everyone wanting the same good for humans.
There would be more spirituality which goes toward self-expression and sensitivity.
"There are two types of seeds in the mind: those that create anger, fear, frustration, jealousy, hatred and those that create love, compassion, equanimity and joy.
Spirituality is germination and sprouting of the second group and transforming the first group."
― Amit Ray.
