He breaks his parole to accompany his family to Cali, which shows a personal loyalty to the Joad family. Tom once again kills a man after Jim is killed by police brutally and unlawfully. A really important factor is that Tom dynamically changes, from one who doesn't care to improve labor conditions, life in poverty, etc., to one who works excessively to advance life quality in these times. A large reason for this is the death of his fellow Jim Casy, so that Tom carried out his work. These facts prove crucial to making the dramatic and strange end to this story
