“One who is injured ought not to return the injury, for on no account can it be right to do an injustice; and it is not right to return an injury, or to do evil to any man, however much we have suffered from him.”
“Violence and injury enclose in their net all that do such things, and generally return upon him who began.”
“The injury we do and the one we suffer are not weighed in the same scales.”
“[...]no one can do an injury to you without doing an injury to themselves.”
“Men ought either to be well treated or crushed, because they can avenge themselves of lighter injuries, of more serious ones they cannot; therefore the injury that is to be done to a man ought to be of such a kind that one does not stand in fear of revenge.”
“I do not like an injurious lie, except when it injures somebody else.”
