Psychologically speaking, I think even though they say they knew it was wrong, they feel that in their case it might be right...Examples might include:
- A guy comes unexpected back to his wife and finds her with another stud so he shoots them both. Everyone knows that murder is wrong and he does too, but deep down he thinks it is right in this special situation...
- A hungry and poor person steals money from a little kid...he knows it is wrong, but he feels it might be just right this time because he is starving...
People are driven by their survival extincts and natural urges to do stuff they would say they wouldn't do...It is the natural conseqeunce of being the only animals with consciousness....
Peace
