How do we develop our ethics? Yes, it is. It subsumes all others, really. This is the standard I use to measure my internal ethical rules and external judgments. Actual reality, once something, anything, happens, does not matter anymore. It can't be judged for it happened (your friend was murdered, you were cheated on a deal, the police arrested the wrong man).
What we often want is that reality didn't happen and we want it changed, when what can be changed is our response. Always respond with love and compassion, even if externally, you have to discipline, arrest or no longer join up with said reality later.
