Who are the bad leaders and good leaders?

It all depends on your point of view. If a leader supports and progresses the ideas you believe in, then you would consider him a good leader. If a leader supports and progresses ideas and laws that you disagree with, then you would consider him a bad leader.

A good leader is one who keeps the people he is in charge of safe from harm; allow them to achieve their personal goals and potentials while respecting the rights of others.
