What is the perfect leader?

What is the definition of a perfect leader? Here is my stab at it.

・She does her best to do anything with other people in the group. She does not just looking and ordering them to do something.
・He is always more diligent than everyone in the group. Rather than he does so with an idea that they will follow him, he always works diligently so they follow him.
・She can consider other people's feelings and situations, and if someone is in trouble, she helps him or her immediately. she is a person who can consider the result of the whole group.
・He always communicates with members of his group frequently to keep relationships between he and the other members. Also, he never forget to keep good relationships between members in his group in order to do anything smoothly.
・She never blames a member for his or her mistake or failure. If there is some problem, she manages to solve the problem with him or her.
・He is always active and bold. He is not afraid of making mistakes, so he can keep trying.
