A human is made of cells , cells are made of atoms , atoms are made of subatomic particles who in their turn are made of energy.
Everything is energy, so there aren't borders between us and in a matter of fact we are not even individual in our materialistic form , but we are all part of the cosmos.
Taken the above for granted because it is pure physics , we can consider doing harm to the cosmos or to others irrational because we are all part of the same body , the cosmos (which literally means the jewel) and while harming others we harm ourselves.
