Killer 7: What The Fuck Just Happened

Just beat Killer 7 and my mind feels like pudding.  Please help.

The Killer7 were a group of highly trained assassins. The US government decided they were a liability and sent an agent to off them. After doing this the agent went a little nuts and adopted the name Garcian Smith, as well as the personalities of all the Killer7 he had murdered (his concousness also altered his reality to incorporate some of the missinformation he learned about the Killer7, such as the television). After that it becomes less clear. The way I figure the fake Harmond Smith and Kun Lao are two god-like beings that, every hundred years or so, choose avatars and see who wins. The old Harmond chose the gov't agent (whose name I can not remember) while Lao made the Heaven Smile. Lao also became Bondage Boy to lead you on your game and keep you from getting lost and giving up the competition. They fought, the fake Harmond won, like he always wins, and they went dormant. If you're looking for explinations for Susie, the hint guy, and bondage boy's wife I do not have them.
