The ship wrecked, I came far-
As a castaway.
My world is shattered, and nothing more remains,
I am alive in deadly waters.

Robinson Crusoe and Prospero were both castaways. Both survived and created their own universe. Yet the shipmates of Robinson Crusoe all died, and the enemies of Prospero, shipwrecked were at the total mercy of him- only he saved them; but he was not obliged. Not everyone survives; it is not even a question of heroism. Heroism is a subjective concept, it is function of favourable circumstances. Think of the person who does not want to be a hero in this conventional way- he does not want to fight back. The legendary Hindi poet Ramdhari Singh ‘Dinkar’ says in a poem, "Forgiveness suits that snake who is dangerous and poisonous, not that snake who does not have teeth to bite and poison to kill". The Bible asks its followers to forgive, if not forget. But the protagonist of the award winning Mahesh Bhatt film Sarangsh has a different concept of heroism. When he tells his wife about his plans of suicide, she accuses him of cowardice, of running away from life. He says, "Do you think killing oneself is so easy? It takes guts to kill oneself." Running away from life may be termed cowardice, but what would you call that spirit which welcomes Death? (See: Epitaph)

This poem does not seek any definition of bravery for its redemption. The protagonist is not fighting anything, because he does not want to, because all that he fought for is now gone. So what is the reason of fighting? If this is heroism, then it is.
