Why?

The reasoning of the study are valid. However it is a more sophisticated way of saying that a person does what they want to do at any given point in time. Unfortunately this is true for all of us. My wife decided she wanted to commit adultery more than not bring unbelievable pain into the lives of those that loved her. Her parents, my parents, our brothers and sisters and friends. The bottom line on these actions is that they are done by people that are incredibly selfish and feel entitled to their own happiness over everything else. Sadly my wife and others actually feel like someone is intruding into their personal business when they are discovered.
