How can you write about "succumbing" to a tragic view of the world and then call for people to "embrace" it? That sounds like masochism or Stockholm Syndrome, definitely not something admirable or desirable.
Do you mean that a person may easily succumb to despair when they suffer misfortune or find the world set against them? And that it is better in this circumstance to embrace a tragic view of the world?
In my opinion, the allure of tragedy rests in this intuitive appreciation of the heroic complex. A tragic view of the world makes one resilient and powerful, fills a life full of meaning, and draws up faith, success and happiness in the face of impossibility from the depths of despair into light of reality, thus transforming a man into a hero.
