The theme of this song is treat others the way you would wish to be treated this is because it shows how what other people did to Vincent (VanGough) affected his life and his work. For example, the line "the silver thorn, a bloody rose, crushed upon the virgin snow" is a comparison of Vincent's work and how we see his work and they saw his work as horrible, like he was insane or something. And it ruined the purity of his artwork and his feelings. Vincent killed himself because of the way he was treated. That's a problem with the world nowadays, we all act as if the world is just there for us and even when life is fair to us we just treat it like a worthless piece of trash. And it can really making other people feel horrible and they would just want out. Thus this songs theme is treat others the way you would like to be treated.
