Why does the President keep lying ?

Trump never developed a conscience. What is right or wrong (for him) is based on whether he can get away with something that is often immoral, unethical and even illegal. He doesn't have a sense of limits. He is always right and "perfect". He views others as inferior, boring, stupid, foolish and ignorant.

To him, the bigger the lie - the bigger the adrenaline rush. It will eventually come toppling down. The question is - who is he going to take with him? 🙄
