I think that we have some responsibility to stand up for the weak against the strong. For example, I don’t think we should let children be hurt by adults.
I think we have a responsibilty to consider the effect our actions have on others. For example, we should recognize that if we pollute water running through our property it may impact our downstream neighbors and we should take steps to address the issue.
I think we have a responsibility to provide care for our offspring.
I think we have reponsibility to live in accordance with the expectation we have of others. Call it social contract, or karma, or the Golden Rule.
