In "The Merchant of Venice," the characters' actions increasingly heightened the existing suspicions among the people around them. As their behavior became more questionable, the atmosphere of distrust grew, suggesting that their deeds reinforced the doubts held by others. This illustrates how actions can profoundly influence perceptions and relationships in a community.

The quote reflects a broader theme in the play regarding the consequences of mistrust and betrayal. As the characters engage in schemes or display dishonesty, it only serves to validate the concerns of those who doubted them from the beginning. This dynamic showcases Shakespeare's exploration of human relationships and the tension created by suspicion.
