Greek mythology

What word decribes why many of the Greek-myth heroes should have tragic ends?

It is the selfishness of the mortal beings and immortal beings!!!!!!.....
actually it start in the desire of someone that leads to war!!! just like in the story of Trojan war, it is between a two men in love in a woman that starts a war!
that even their goddess got involve because they wanted to revenge!

You mean Hero-Archetype? This was a pattern that was seen in the lives of most legendary heroes, that included struggle. To suffer was synonymous with heroism, back then.

The word in Ancient Greek is 'moros' which means one's alloted fate. All the Greek heroes had this but they could change it, like Odysseus does when he blinds Polyphemos, the Cyclops - then he gets more 'moros'!
