I think that there's something more fundamental. Lying and deception are not inherently wrong. What's wrong is degrading the human situation.• Lying is to make a deliberate false statement.
• Lying is usually verbal.
• Deception is causing to believe something false.
• Deception can both be intentional or else unintentional in which case the person becomes self-deceived.
Saying, "Oh no, it's no problem!", when you're lying to assuage the feelings of someone you're helping is not a bad thing.
And much damage is done by telling partial truths. Saying things that are true, but don't accurately reflect the reality.
The political and media world is especially full of that.
To me, this makes it obvious that there is no "objective morality". Lying and deception aren't wrong, what's wrong is degrading the human situation, and people often have different opinions about how things *should* be.
