Okay... instead of asking "can you lie?", how about "how many lies you have told people?" - just like we can assume that no body never lie.
Whether or the villain character of the anti hero book, or saint from a certain myth. People told lie, didn't they? Okay, you may believe that certain people don't lie.
But the question is, can you lie? It's not about other people... but you! Can you lie? It's not about the past you, or the future you, ... but you! Can you lie?
Look at the question, and may you find yourself.
