Here's a question: does Sonnet 94 actually recommend hypocrisy as legit? It sure seems like it. In the beginning of the poem, the speaker mostly speaks about the powerful people's hypocrisy in an admiring way. He is really impressed by their ability to keep themselves hidden, to influence other people without being influenced themselves, and to be the "lords and owners of their faces." By the end of the poem, though, he seems not only to admire hypocrisy, but also to be actively recommending it. What's up with that, Big Willy?
Sonnet 94 shows that hypocrisy can have some positive aspects, like when people seem like they could hurt you, but actually don't.
The speaker seems to be recommending hypocrisy, if it can prevent you from letting your negative qualities appear for the world to see.
