Ghosts don't need remorse to qualify for a class A haunting.
Bush will be haunted until he dies and their souls drag him to the caves of the Dark Lord, all the while screaming for Cheney to come and help him. Only to see Cheney when he gets there, dressed in a hunting uniform, getting shot in the head repeatedly every five minutes.
I still find it hilarious that his portraits are all of people from the first page of GIS results when you google their names.
These are people he's met. SURELY he's got actual photos of them somewhere, but no, his assistant grabbed the ol' laptop and gave the minimal effort. Which, I suppose, is part and parcel with Bush's talent.
