SPOILERS!!!!!
Chase DOES suck in some of the game, but that's somewhat to blame on the hum(the hysteria), somewhat to blame on Samuel(us), and somewhat to blame on Chase Himself. I'm pretty sure the hum "amplifies" the "Crazy" traits of someone, be it Leo's obsession with Chase as seen by The Embrace, or Jenna's craziness in the bad end of her route. I don't believe that Chase is blameless, but I do believe that he isn't entirely at fault.
..But then again, Leo causes Chase to lose his feet in the bad end, so Leo IS covered in red flags.
