Alexander the Great?

Alexander does deserve to be called the great. He demonstrated incredible abilities even at a young age by taming a horse that professionals couldn't control. He demonstrated great charisma and tactical skills with his armies. He persuaded a homesick army to continue fighting and traveling to defeat bessus, despite Bessus not even being a true enemy. They followed bessus, purely because of Alexander's personal vendetta. Although he was a drunkard and seemed to have no purpose other than revenge, he was tactful and charismatic and a powerful leader.
