Elders are like cops...
Some cops want to be cops to help people, make a difference... some cops want to be cops so they can carry a badge, a gun and have a position of power over those who don't have the power.
Some elders are sincere and want to be a shelter in the storm. Others enjoy the power and position. They like to be in charge, hand down rules and enjoy disciplining people.
I think it comes down to what part of the Bible connects with them personally. Some are attracted to the Christian principles of Jesus while others are attracted to the power and black/white rulings of the Mosiac law under the Hebrew God Jehovah.
