It is impossible, because you quickly run into contrafactual history.
Let's say the descendants of Scandinavian vikings owe repairs to descendants of people living in Normandy, because the vikings raped and pillaged.
Except, they also settled. And became Normans. And invaded England. Changed the English language forever, changed the ruling class of England. Changed the history of Europe forever. Maybe the Norman conquest was ultimately a good thing for England? Maybe the Anglo-Saxons would have been wiped out by some other conqueror if the Normans hadn't come?
There are millions of people who live today because history happened the way it happened. If the vikings hadn't raped and pillaged and settled in Normandy, those millions of people would never have been born. So do they owe money to the descendants of the vikings as thanks for their existence?
