Answer:
A good symbol in Romeo and Juliet is the poison. In Act 2, scene 2, Friar Lawrence says that every plant, herb, and stone has its own special properties and that nothing exists in nature that cannot be put to both good and bad uses. Poison is not intrinsically evil, but instead it's a natural substance made lethal by human hands. Friar Lawrence’s words prove true over the course of the play. The sleeping potion he gives Juliet is made to cause the appearance of dying, not death itself, but through circumstances beyond the Friar’s control, the potion does bring about a fatal result: Romeo’s death. Similarly, Romeo suggests that society is to blame for the apothecary’s criminal selling of poison because while there are laws prohibiting the Apothecary from selling poison, there are no laws that would help the apothecary make money. Poison symbolizes human society’s tendency to poison good things and make them fatal, just as the pointless Capulet-Montague feud turns Romeo and Juliet’s love to poison. After all, unlike many other tragedies, Romeo and Juliet doesn't have an evil villain, but rather people whose good qualities are turned to poison by the world in which they live.
