A) The Point Of Carl's Decision.
             By the end of the movie Carl is put in a position were he must decide weather or not he should just leave like has been told to do, or do something to help young Frank.
             Carl has many options which he must think about including: leaving Frank and his mother to fight there own problems, go to the police, take Frank and his mother away, and kill Doyle in order to protect the family.
             I personally think that Carl should kill Doyle.
             Carl has been in a position where everything is out of his hands; he had no freedom to make his own choices or decisions for the most of his life. After getting out of the hospital Carl has no idea of 'how the world turn' and no idea of what to do with his new found freedom. And like many other people, who have been in Carl's position, he just wanted to get back into the hospital.
             If Carl does kill Doyle then he will most likely be returned to the hospital and his way of life, which is what he wanted right from the beginning. Once Doyle is dead Frank and his mother will be able to enjoy their lives, as they deserve to; they are nice people whiling to help those in need and befriend those who are rejected by society.
             There may also be some unpleasant consequences for his actions that I am sure he would not like to deal with. After this he will never be trusted again by most, maybe Frank's mother will never trust him again, never allow Frank near Carl again. He will be feared by all. This time he may not return to the hospital ether, this time he maybe jailed – treated like every other murder.
             Unfortunately these are all things that Carl must decide on his own. Fate deals weird hands some times and Carl has just been given a mean hand that he doesn't deserve. No one can help Carl make his mind up, for in Carls heart lies the answer he wants. Carl will do what he feels is the right thing to do and nobody will be able to stop
