Question: I'm trying to accurately describe a person who acts in one way and does another but knowingly and openly accepts that his actions also include him in the same group he criticizes.

This differs from a hypocrite who condemns those who perform an action but justifies his own actions by unrelated means and does not accept he is a part of that group.

Does such a word exist or is there a better way of describing such a person?

[Merriam-Webster](http://www.merriam-webster.com/dictionary/hypocrite?show=0&t=1292603911) defines a hypocrite as a person who acts in contradiction to his or her stated beliefs or feelings.

Answer: 
I have heard someone use

> 
> I am a prophet, not a saint.
> 
> 
> 

A *prophet* is one who comes to the world to give us a message. Here it refers to how he criticizes others for their wrongdoings.

A *saint* is one who does good things. Here it refers to how he does the same bad thing that he criticizes others for.
If you don't mind it as an adjective, this person is either:

**insincere**

or

**disingenuous**
