-Esav had all the powers of the harsh judgments (Midas Hadin)
-Originally he could have used them for good that’s why his father liked him. After he went all out for the other side, Yackov had to start taking over his job. That is why he stopped acting like a ‘simple man dwelling in tents’.
-Meaning, Midas Hadin exists, it just has to be used for Keddusha.
-If there is no one in Yisroel making themselves into a chariot for the Gevuros, they will be used against us, that is what happened during the Holocaust.
-We have to get there before they do. That is why we are commanded to wipe out Amalek, which seems like a cruel act that goes opposite the nature of Yisroel.
