What is a "noble lie"?
Were lies told to Nazis for the purpose of protecting Jews not for a noble purpose? I think that most reasonable people would agree that lies told to protect the innocent from harm are examples of noble lies.
Any lie is still dishonest and is always tied to the benefit of the liar. Even a lie to spare someone's feeling is actually a lie to keep the lie teller from having to deal with the hurt feelings of others. God has no need for such human folly.
Yes, all lies are examples of dishonesty, but dishonesty does not always serve a selfish purpose.
Lies and dishonesty are basically forms of deception. Deception is nothing more than a tactic. Like any tactic, deception can be used for good and it can be used for evil.
