A.N. — Here's a decrepit dude who was warped by his family environment. I still don't think he'd have been elevated much beyond that even without the Black/horcrux crazy affecting him.
93. Kreacher
Kreacher's head would be mounted proudly up on the wall one day. Then, he could finally look down upon those despoiling his family's house.
Mistress Walburga was but a portrait, and he was so very old and tired; there was little in his power to stop the Order of the Phoenix from using Grimmauld Place. But Kreacher could refuse to listen to everyone's orders, and hoard valuable heirlooms in his little hidey-hole den. He didn't need any orders to so; indeed, openly defying the blood traitors was one of the few pleasures left in life for the wizened house elf.
