Modern tragedy

One of my favorite movies of all time is Seven Pounds, starring Will Smith.  It was release in late 2008 and is about a man, Will Smith, who accidently kills his fiance and six other people in a car accident.  He was texting while driving and was distracted  and then he hit another car.  Will Smith is devastated by this, and rightfully so.  After this incident he decides his life is not worth living anymore.  His decision is to find people that need organs and sacrifice his life so that they can live.  He, in the end, finds those people and donates seven pounds of his organs, hence the title.  This movie is a tragedy because a successful happy person has a downfall due to his own flaws.
