Even if it is about Kanye, I think of it as a song about just forgiving somebody for what they've done to you and moving on. They're still innocent. Everybody has messed up before. Even though they messed up, they still shine bright. It's not about what you did, or what you've said to somebody, it's you as an individual and you can always fix mistakes. There's always that chance to start over with someone.
