You just defined yourself as being selfish, relegating others to obscurity and despair just because you don't think they're worth helping. Who the hell do you think you are to decide that about other people? They're sick and in need of help, and if you'd deny them that because you don't think they deserve a chance at redemption then you are absolutely selfish, not to mention remarkably full of yourself. Not everyone can necessarily be saved, but every life is worth trying to save anyway, no exceptions.
