why does victor think he survived all that he had been through? how is the fact that he lives ironic

Victor longs for death, and finds his ability to survive such an epidemic of tragedies bitterly ironic. He thinks his survival is a penance for his horrid creation. He concludes that he was, after all, "doomed to live." Death would be too easy for Victor. He is doomed to suffer in life.
