Here's a breakdown of the song's meaning:
* The "Death on Two Legs": This refers directly to Norman Sheffield, who the band felt was exploiting them and taking advantage of their success. The lyrics paint him as a greedy, manipulative, and untrustworthy individual.
* Themes of Betrayal and Exploitation: The song expresses the band's anger and resentment towards Sheffield. They feel he's betrayed their trust and exploited their talent for his own gain. Lines like "You're a cancer, you're a curse, you're a blight on everything good" and "You're a leech, you're a viper, you're a plague on society" highlight this rage.
* Justice and Revenge: The song concludes with a sense of justice and retribution. The band wants to expose Sheffield's actions and ensure he doesn't harm anyone else. This is implied in lines like "You'll get yours, you'll get yours, you'll get yours in the end."
It's important to note that this song was written during a time of great tension between Queen and Sheffield, and the lyrics are meant to be interpreted through that lens. While the song paints a very negative portrait of him, it's important to consider all sides of the story before forming a definitive judgment.
