I don't think he killed any witches. If we're going to believe the intro, there is only a few witches, and the ones that we know of in-game are the Bed of Chaos, Quelaag, Quelaag's Sister,Quelana, the witch close to the BoC, Ceaseless Discharge and the corpse that he's protecting.

He probably just joined the Chaos Servants or maybe he is from a time before the BoC was created, and was teached by one of the witches. (Like Salaman and possibly the Chosen Undead was.) He then travelled to Anor Londo where he, for some reason, was banished to/trapped in the painting.
