Most leaders these days are bad influences and not suitable to be emulated. Their lifestyle is "do as I say and not as I do".
A leader is meant to be of a great service to followers but unfortunately leaders these days abuse their position in several ways.
There are many good leaders out there, but probably not so much in politics which is, I guess, what your comment is about. Most are driven by greed or ego. Political leaders tend not to be very good at leading, although that depends on perspective also I suppose.
I guess all we can do is be a good leader for those who depend on us, family, friends and self and hope that's enough.
