So that puts him with the title of "alexender the barbarian" instead of great; what great was it about him by destroying Cities-Nations-killing civilian population. By the logic all invaders-conquers should be The Great, jeez history is really twisted.
It is evident that you hold a grudge for a historical figure. Tough luck mate, the guy is dead and you can't do anything about it.
Not only that, but he is and will forever be "Alexander the Great" and he is one of the very few men, rulers, conquerors, strategists, leaders, generals, pioneers, that will be remembered forever.
He changed the world leading by example. You have a problem with that, it is a personal issue and not a historical one.
