Which are the qualities of Achilles?

He was a fierce and courageous warrior who slaughtered many opponents. He raped boys, got in a petty huff when King Agamemnon stole his girlfriend, and refused to fight - until his friend and lover Petrocolus became so ashamed that he stole Achilles' armour and went into battle pretending to be Achilles. He was killed, which brought Achilles back into furious action, where he killed a Trojan leader and proved his manhood by dragging his body around the walls of Troy. Persian prince Paris laid him out with an arrow, ending his brutal and immoral life.
