Mr. Rager

I think the meaning to this song is very prominent in the video for it. If you haven't seen it, then you must, or else this explanation probably won't make much sense...

Scott is unstable emotionally, as shown by him talking to a psych. Mr. Rager is Scott in the spotlight, or how we all know him, as Kid Cudi. His dreams lie at the top, and he's running up the stairs to claim them and not willing to come back down. I don't know Scott, so there's no way to tell, but I believe his dream is normalcy and sanity. But he has to fight for them, and overcome obstacles along the way in the form of critics, emotions, fate, whatever, and he's clearly overwhelmed, but not willing to give up what he wants, or rather, needs. From above Scott, the actual normal man, watches him, and he knows that Mr. Rager won't ever be able to reach him up in his sanctuary, so he goes down to meet Mr. Rager. And when it comes time for them to finally meet, Scott kills Mr. Rager, not maliciously, but gently and peacefully, because killing Mr. Rager is the only way for Mr. Rager to achieve normalcy and sanity.
