Ravenous Bugblatter Beast of Traal
Every Paladin archetype implies an alignment, with a suitable code accordingly.
This is demonstrably not true in 5e. In 5e there are no required alignments for any of the subclasses. I've personally played two different Oath of Ancients paladins with different alignments, one CG and one NG. They had the same Oaths and focused on them in different ways.
