Meaning of "Digging Graves" by King Diamond

The lyrics of "Digging Graves" hint at a deep-seated resentment and desire for vengeance. The speaker seems to have undergone a significant transformation, perhaps due to being institutionalized or traumatized in some way. He is obsessively fixated on Lucy, whom he blames for his current state of being. The act of digging graves and leaving headstones symbolizes his intent to make Lucy suffer eternally, mirroring his own inner torment. The repeated lines about being someone's misery and wishing them well in hell suggest a twisted sense of satisfaction in causing pain. Overall, the song delves into themes of madness, revenge, and the darkness that can consume the human soul when driven by hatred.
