If it's not right, don't do it. If it's not true, don't say it. Keep your intentions and decisions free from pressure and force.
If it be not fitting, do it not. If it be not true, speak it not. Ever maintain thine own purpose and resolution free from all compulsion and necessity.
When you think someone has done wrong, ask yourself this: Do I really know if this is actually a sin? And even if it is, how do I know he hasn't already judged himself for it? That would be like a man clawing at his own face — something to pity, not to anger. Besides, expecting a corrupt person not to sin is like expecting figs not to have moisture, or children not to cry, or horses not to neigh. It goes against nature. What else can someone do when that's their character? So if you have the power and skill to help them change, then do it.
At the conceit and apprehension that such and such a one hath sinned, thus reason with thyself; What do I know whether this be a sin indeed, as it seems to be? But if it be, what do I know but that he himself hath already condemned himself for it? And that is all one as if a man should scratch and tear his own face, an object of compassion rather than of anger. Again, that he that would not have a vicious man to sin, is like unto him that would not have moisture in the fig, nor children to welp nor a horse to neigh, nor anything else that in the course of nature is necessary. For what shall he do that hath such an habit? If thou therefore beest powerful and eloquent, remedy it if thou canst.
