No one. Cause is not think "help humanity" nobody can help or save those who dont want to be saved. Liders rise above the society from time to time and became "masters","iniciates" or guides; but all try to teach the same "love" "reason" and the fact: anyone can be a leader only if he/she chosse it.. The dead leaders know this Jesus, Buda, Luther King,etc. and they will live again if the want it we dont need do it for them. Even they live in the hearths of all that understand them and care
