I'm a bit worried about oathbreaker honestly, hope it doesn't trigger to quickly. I'm sure that what is considered to break the oath can be debatable. Having it automated might make me rethink choosing paladin but we'll see
Breaking an oath is automatic, you need to show remorse/atone for it. The discussion with the Oathbreaker Knight probably has a path where you can show remorse and not go Oathbreaker. There might be a hidden limit to how many time you can weasel out thought.
