I always had this feeling that Kreacher wasn't bad but.. broken-
Becuz as written in the book...
he elf quaked from head to foot. “Kreacher drank, and as he drank, he saw terrible things . . . . Kreacher’s insides burned . . . Kreacher cried for Master Regulus to save him, he cried for his Mistress Black, but the Dark Lord only laughed . . . He made Kreacher drink all the potion . . . He dropped a locket into the empty basin. . . . He filled it with more potion.
I feel so bad for him, but later harry gave him a locket and he became sweet and innocent and stopped calling them names like- "Mudbloods" or "Blood Traitors".
Proof Kreacher is Sweet! 😏✌
