Lies are morally wrong, then, for two reasons. First, lying corrupts the most important quality of my being human: my ability to make free, rational choices. Each lie contradicts the part of me that gives me moral worth. Second, lies rob others of their freedom to choose rationally. When A lie leads people to decide other than they would had they known the truth, harmed their human dignity and autonomy. Believed to value ourselves and others as ends instead of means, we have perfect duties (i.e., no exceptions) to avoid damaging, interfering with, or misusing the ability to make free decisions; in other words - no lying.
