Our society has demonized death to the point that almost everyone is scared of it. Everyone is sad when a friend or a family member dies. But it doesn't have to be this way. Death is not inherently a bad thing. Nowhere in the fabric of this universe is it written that death is bad. That whole idea is just something people made up.
Imagine if books had magic in them that forced you to finish the whole book once you started reading, even if you hated the story. That wouldn't be nice at all, would it? Life is the same way. If you don't like the story, it's okay to close the book and move on. It's up to the reader to decide if the story is worth continuing.
