Human beings are foolish and have insatiable desires. Expanding ambitions are always influenced by interests, seeking benefits and avoiding harm, selfish and self-serving. Therefore, altruism and fairness do not exist. People occasionally do good deeds merely as a disguise to gain fame and profit. Even the best individuals can easily become corrupted and degenerate because doing evil is more beneficial to oneself, and lying pleases others more. If I stand at a high position, there will be great scholars to argue for me. Machiavelli famously said that as long as the goal is correct, any means can be used.
