The finger pointer is pointing, but it may be trying to point back. Some folks have a bad habit of always pointing out to those who are living a life that need changing; using the finger pointing, I told you so.
Some just shake the finger back and forward saying shame on you. You know people should remember how they used to live.
There is another word for those who are the pointer, self-righteous. These people can cause more harm with that finger pointing then anything. They forget where they came from or what they were at one time. I think we should be careful how we used the finger. Help those who caught into the trap of things that will cause them harm and bring disrespect.
Always know that the finger can point back; therefore, be kind and remember the God that pulled you through your mess can pulled your brother or sister out of their bad situations.
