Honestly, this is the true power of friendship rather than trying to force him to coddle and get along with those people.
Racist elves, corrupt nobles, selfish and incompetent party members. Hell, one of the most reasonable people in that world is the elf prince and most players kill him rather than getting rid of the hypocritical father and sister.
