Someone deceiving with conscious intent can apply more compute / intelligence and other resources for optimizing and maintaining the lie, which means the deception can be much bigger and more consequential, thereby causing greater damage to others.
Unconscious deception is hard to distinguish from innocent mistakes.
Surely someone consciously intending to deceive can apply some of that extra compute to making it harder to distinguish their behavior from an innocent mistake.
