Secondly, leaders are required for high moral and ethic standards, which ask them to take their possible outcomes of principles and objectives they commit to into consideration. Otherwise, they cannot persuade the public to obey their orders, or, even worse, cause disastrous result to the society if they gain supports. In my opinion, popular opinions have often gave their reasons of existence, or they cannot be accepted by public. Despite of the possibility that people are misled,every people has their ways to think logically. So when the leaders' principles and objectives conflict with public ideas, they should concern why such confliction take place, and make their decision after a careful scrutiny. Adolf Hitler, an undoubted leader who committed to his will of conquer and racism, even persuaded the German in 1930s to follow him. The autocrat was holding on ideals which do not meet humanity and morality, causing the world suffer from millions of death during the World War II. The Hitler's lesson tells about the importance of other qualities of a leader which may be needed when establishing his particular principles and objectives.
To sum up, leaders are asked for many qualities besides their consistence committed to particular principles and objectives and such principles and objectives should be careful taken after considering about the society's material situation. As long as the leaders in every field keep an open mind to popular opinions, and as long as they think comprehensively on the reasons and reality, they will certainly lead us to a better future.
