Cover art for Ruiner lyrics by Nine Inch Nails

i think the ruiner as refered to as a person is supposed to be god or a form of one, someone better than he is, to tell all the people the answers to questions they didnt know, and how this reflects on him, his is nothings, all the fucked up things he thinks and feels is a result of someone having all the answers, detering attention away from him or what he has done...one of my favourite NIN songs...

this song is about a sociopath

Perhaps a Scorpio? One who defines this astrological sign perfectly? Probably not, but I think it fits well.
