If you become leader, so-called leader, rascal leader, and you are addicted to illicit sex and intoxication and meat-eating, you must be sinful. If you are sinful, how you can lead persons? Andha yathandhair upaniyamanah [SB 7.5.31]. Blind man is leading other blind men. Therefore there is no solution. Why the world is in chaos? Because the leaders are all sinful.
