It is not possible for any one person to maintain 100% awareness of the entire planet, nor is it feasible for
most people to simply live in the woods as a hunter-gatherer and take nothing from others who might do wrong elsewhere.
Once we accept that each of us is a human rather than a morally perfect literal supernatural angel, each of us must decide: If we cannot sanction all wrongdoers, does that mean we sanction no wrongdoers, or some?
If some, how do we decide which ones? One good metric would be "minimum impact on my own life". Another would be "amount of badness I'm personally aware of that entity doing". A third would be "how closely is the entity that I'm actually affecting ties to the group committing the atrocities?"
So; I personally sanction some countries that commit atrocities, one of which is Russia.
