I'd guess the guy you know is more of the ruined bum Lena encounters, and Seymour is the guy who has fucked him over.I just compare Seymour to another rich guy I knew here, he did practicaly the same as Seymour, but geuss where he is now?
Yes he is poor and ruined, because another rich guy fucked him over and does things right with his riches, ok Seymour can feel the power and is addicted to it, but eventualy it a recipe for disaster and there always be other rich people fucking them over.
