Love Ben's voice, he just carries this along. The message here is about the greed of man, and what he feels when he commits a crime. Superman is the target for what he felt when he accidentally kills Batman or another good person or just goes too far when beating a villain or when he commits a crime himself and shows that no matter how good you may think you are, you are still human to an extent and thus can be influenced to commit a bad act without a thought of it. Like unintentional murder, or thieving for your life or otherwise.
But I love this song so much, I wish I could hear him sing it live though.
