I'm the villain, the killer of all that's pure

I'm the villain, the killer of all that's pure I spit fire, leave haters on the floor, insecure I'm the nightmare, the darkness in your dreams I'm the one they fear, the one who reigns supreme I'm the one they call when they need a hit I'm the one they fear, the one they can't forget I'm the one they hate, but they can't deny I'm the one they love to see, but they'll never try I'm the villain, the one they can't control I'm the killer of all that's good, I take a toll I'm the one they whisper about, the one they fear I'm the one they can't escape, I'm always near I'm the villain, the killer of all that's right I'm the one they can't defeat, I shine bright I'm the one they envy, the one they hate I'm the one they can't escape, I seal their fate or
