Alexander was a genius and an inspiration to men.
He is over villified in today's society and deserves to have much more credit than he gets. Alexander had a vision and was determined to follow it through. He loved his men and army as much as they loved him. He didn't return Porus to his kingdom because he lost the battle, that's rather bizzare as a matter of fact. He returned him because he had a deep respect toward others, especially the ruling monarchs and to those of you who actually have read into the history of Alexander, this would have been made evident everywhere.
Such as the incident at Issus when Darius fled and left his family there, including some of his daughters and his mother, Alexander had such respect for them he never harmed them nor threatened them in any manner. Alexander was an hounourable man.
Not only did he return Porus on his throne but he gave him more territory to govern than he previously had.
How about the time when some of Alexander's troops found a little water while they were on their march with all men suffering from hunger and thirst, and they gave a helmet full to him, Alexander tipped it on the ground in front of his men and declared he won't drink until his men do. Alexander was willing to share everyhardship with them.
And of course he wanted to excel others in history, that made him a extraordinary person with motivation and drive.
I'll leave this with a quote from Alexander on his deathbed, this shows alot about the extradorinary person he is.
"After my death will you find a king who deserves such men?"
