It amounts to the same thing. The abbot once told me that lying was a betrayal to one's self. It's evidence of self-loathing. When you are so ashamed of your actions, thoughts, or intentions, you lie rather than accepting yourself for who you really are--or, in this case, pretend something happened when it didn't. The idea of how others see you becomes more important than the reality of you. It's like when a man would rather die than be thought of as a coward. His life is not as important to him as his reputation. In the end, who is braver? The man who dies rather than be thought of as a coward or the man who lives willing to face who he really is?
