Karma Houdini implies that he was never sufficiently punished for his actions: not only was Horace executed, but his ghost has spent the last few years bound to the electric chair in a state of perpetual torment. Not exactly getting off scot-free.

Also, by nature, if he's been redeemed as the categories suggest, he probably doesn't count as a karma houdini either.

Plus,  it's implied that the boss battle freed him and he might just be able to move on from the island altogether.
