Exactly like that. It doesn't have to be that perfectly rigid if you don't want, though. You could be a Robin Hood-type thief, who only uses their skills to provide for people who have less than they do. Or you could be a Paladin who's been twisted up and spit back out by their Oath of Vengeance or a Cleric who began serving the Tempest after they survived a shipwreck that killed the rest of the crew. Any story you want to tell, you can make it happen.
