Whether the man was actually a descendant of Amalek or not is not the point. It is well known and accepted that Hitler and the nazis y”s are considered the “spiritual” descendants of Amalek. I dont think it was merely “psychological support”. The idea is that Rav Kanievski knew that the soul of the man was from Amelek. (If you had the opportunity today to put a bullet thru Hitler’s head, would you hesitate?)
