Cover art for Pigs Is Pigs lyrics by Every Time I Die

He killed his wife, but he isn't getting away with it in the typical sense. He's being put to death but he considers it a good thing, because he's being given freedom from love. Love is the prison that he's already been living in, and he considers it a "crime".

"We're liberated by the hearts that imprison us We're taken hostage by the ones that we break"

Here's the way I take this... Ironic. The only way we can seek happiness or emotional comfort is by embracing love, and we're forced to do so-- we can't live without love, it's our prison sentence for being human and alive. And when we hurt someone, the guilt never leaves us, because his/her pain stays with us as well.

Overall the song attributes love to guilt. We are forced to love but it is (implied to be) impossible to do so without committing a crime, the sentence of which is to live with the guilt. The only freedom is death. A pretty heavy allegory.
