Here, "doomed" means to have an unfortunate and inescapable outcome. It's destined to fail. It's used to describe things that will end badly no matter what. Ex: We're doomed if our parents catch us sneaking out. Ex: The plan was doomed to fail. Ex: The dog was doomed to the streets if we didn't take it in.
