So here are some new alignment related ways of earning XP to replace the originals. They are useabke across all classes.
Good- teach (defeated?) villain the error of his ways in heart to heart talk and tell him of path to truth/justice/light/goodness.
Evil. Harm/kill those who help you and wish you well.
Neutral. Revenge yourself against those who harm you or reward those who aid you in degree which they deserve.
Lawful. Uphold/enforce the law system you believe in .
Chaotic. Cause contention or controversy or disorder in your party or among the people your around.
P.S. I think dungeon world is one of the best RPGS for creating characters or drama like that from your favorite movie or show due to how freeform and engaging the rulesystem is.
