When what someone says can be interpreted in multiple ways, we are in danger of coming to an understanding which is different to their intended message.

When one wants to justify the harm one has done by saying that others have done the same or that this evil was only a reaction to the harm done by someone else, they commit the logical error of appealing to hypocrisy.
