There is thy gold, worse poison to men’s souls,
Doing more murders in this loathsome world,
Than these poor compounds that thou mayst not sell.
I sell thee poison; thou hast sold me none.
– William Shakespeare
Romeo and Juliet, Act 5, Scene 1. As Romeo pays the poor Apothecary for the poison, he says that money and greed are a worse poison to men and their souls. Romeo sees money as a kind of evil that causes more murders that any amount of poison sold. Comparing gold to poison is an example of a metaphor.
