A hypocrite holds other people to a standard to which they will not hold themselves. It is easy to point fingers. Still, such things do come back around.
There is nothing wrong with decrying evil in the world. But you must first deal with what you find inside. Otherwise, no one will hear what you have to say.
High expectations are the burden of the good. Someone who claims better must prove it by their actions. Once credibility is lost, it may never be regained.
Evil people are not expected to be anything else. They live and die, wondering why others do not care. Such have no concern for the woes of those around them.
If you do good, it will come back to haunt you. People will expect a level of perfection heretofore unseen. Self-righteousness leads to self-aggrandizement.
It is always best to lead by example. Why follow someone who does not know where they are going? Only the ones who shine could ever light the way.
