Can someone please revise/edit my intro paragraph?

A tragic hero is a character in a work of fiction who struggles in life, preserves against all chances, but seemingly ends up dying in a cruel twist of fate. The hero’s downfall is his own fault as a product of his own free choice, but his misfortune is not entirely deserved. He discovers fate by his own actions, and not by things happening to him. In the novel, The Scarlet Letter by Nathaniel Hawthorne, Arthur Dimmesdale becomes a victim to his own destruction, and although his sufferings bear meaning, they are not wholly deserved, thus making him a true tragic hero.
