As I said, Hamas would kill all Jews if they could. They are no different in intention from Hitler. So Hitler's intention isnt unique.
Even his action isnt unique.
Allies designed bombs which were specifically made to burn civilians alive inside their homes.
Stalin killed at least 7 million Ukrainians and has also killed plenty of his own people.
Mao killed 40 million of his.
Even after Hitler, there were plenty of mad leaders killing people.
Hitler is just much more mentioned, but in terms of kill count, he isnt number 1 in the century, and in history there were always crazy leaders who killed millions, one way or the other.
