accident makes a different life

a car crash. two men torturing each other.bringing about great changes to belief and life. one holds the belief and purpose to do the right thing ,but life has played a big joke on him.everyting just turn into chaos. just in one day. the other has a strong belief in law. when on is in trouble ,or rather, in danger of career,honour,raputation, one can do whatever it takes.
 although they have done harm to each other's life ,they try to fix it. yes ,to do the right thing.
 maybe that's humanity?.we should have faith in that.
