Satan is the father of lies, and you are saying that lying to your children is a good thing. OK then.
Here is my explanation of Santa: Santa is the spirit of Christmas which is the concept of giving without expecting something in return. It works whether there is a man in a red suit or not.
Your inference is incorrect. I did not advocate lying to as rearing parental technique nor as a routine way of dealing with children. Despite your absolutist and assuming diction, no one is perfect; Romans 3:23. Notwithstanding that truth, forgiveness is at hand. Even for you.
