Psychological Criticism Product of Our Enviroment

Pyschological criticism is when a character may be examined based on their upbringing to made reasoning for their actions.  An example I can think of is in movies, especially when you watch thrillers.  There are those movies where the killer came from a broken home or he was sheltered and never knew the outside world, of which made that character kill someone.  Another example of psychological criticism would be one that I can relate to more.  The charcters in movies that come from a poverty ridden neighborhood and always lived around drugs and gangs.  The character also ends up in the gangs or selling and using drugs.  A great phrase that I can interwine with this lesson is we are a product of our enviorment.
