The Rothschild of course, but my guess for most destructive in ALL OF HISTORY would be the leader of the byzantine betrayal in the early 500s ad(513? 515? Idk).
This betrayal led to the byzantine exiling them, causing an exodus north of the Caucasus to settle into what was once Kazharia, using their tried and true phoenician tactics to subvert the local populace and eventually install themselves as an ethnically distinct ruling class. The peasantry benefitted from the jew overlords malicious trade schemes and so adopted the culture(as all peasants do - emulate the elite). When the kievan rus finally had enough of their bullshit and wiped them out, the Jewish overlords who had developed an extensive trade network with the western European noble houses fled and installed themselves into them as advisors and merchants. The peasantry fled westward and settled in the Rhineland. Those peasant are what we know as ashkenazi jews. The elite are still the elite, using the last thousand years to subverting and subject the great noble houses with debt and wars and conflict, always keeping their true loyalty to their original people.
Without that there would be no rothschild.
So that guy. Whoever he was.

Without that kike cunt, the ubiquity of debt slavery (aka compounding interest loans) and the entirely Jewish banking cabal that has served to advance Satanic (i.e. Jewish) interests to an astonishing degree for the last three centuries. It was the Rothschilds who orchestrated countless brother wars and pointless conflicts- beginning from the 1700s, not just recently. It was the Rothschilds who sabotaged Bonaparte after he began forcing kikes to cease with their kikery, who came after President Jackson when he killed the Second Bank of the United States, who piped one of their own (Lincoln) into the White House, who partnered with Rockefeller (another top contender for most evil man in history) to enforce a global oil cartel which they had a controlling interest in...
...need I go on? All of this and much more began with Mayer de Rothschild and his instructions to his sons, telling them to always take opposite sides of any conflict, loaning to one another's interconnected banks without interest or question, to always support their fellow sons of Satan, no matter the immediate cost.
