Lying does not need to be justified, it's pretty harmless by itself. If I lied and said I was the Supreme High Chancellor of Mars, who would care?
It's only when lying is used for deception that trouble begins.
Deception and lying are two very different things. Sure, you can deceive people with lies, but you can also deceive without lying and lie without decieving.
What's the difference? Dictionary.com defines lying as:
noun
1.
the telling of lies, or false statements; untruthfulness: From boyhood, he has never been good at lying. Synonyms: falsehood, falsity, mendacity, prevarication. Antonyms: truth, veracity.
adjective
2.
telling or containing lies; deliberately untruthful; deceitful; false: a lying report. Synonyms: deceptive, misleading, mendacious, fallacious; sham, counterfeit. Antonyms: true, candid, actual, correct, accurate, trustworthy.
Lies are false statements intended to deceive. You say tomayto, I say tomahto.
Or entertaining. What is a work of fiction but an elaborate lie created with the intent to entertain rather than deceive?
Fiction is an imaginary piece of work intended to entertain, not deceive.
Lying and deception are synonymous.
I grant you that many people do lie because they want to be entertaining -- that is often their sole motive. But my experience is that they still get upset when they are called upon it, no matter how gently or no matter if you even try to give them an out and pretend that it was an open joke all along.
Huh?
