Our educational systems need to change in order to reflect the advanced evolutionary stage we're at.
Revenge is just another word for give-and-take. Everyone causes consequence, through sequence of action. The time and space that the scalar effects come back to you varies with the spacetime set.
Example: tape your wrists, waists, and ankles together to another person. The range of sync you enact is also in scale to the size of the spacetime set. So, therefore, a butterfly causing a hurricane on the other side of the world is going to have a longer, more delayed wave effect, than you taped to another person.
The Golden Rule.
So if one were well educated to scalar options of the what, where, how, why, when, and who, then initiating (first cause) eventual consequence becomes just as moral as the agent's accountability for scalar return.
So, assuming six degrees of separation, do we need to be more accurate in the what, where, how, why, when, and who's, given that the ratio of people-to-resources is becoming just as important as our control of life-changing power? Or is it inevitable that a species goes through a thinning-of-the-herd, and a large percentage of people get left behind and become obsolete in the genome?
Perhaps both options above are true, and it's exactly the rationing of how much - the very measure of scalar, educational philosophy, that is most crucial.
