Sure. Perception matters. That said, we are going afield a bit. I'm talking about how class abilities affect roleplay, not whether or not you can make claims in the game world and how NPCs might react to such claims.I mean the PC could have been anything and killed said NPC father for zealous reasons and have the same effect. Would said NPC hate paladin's or hate anyone who calls himself a paladin and is a member of a certain sect.
so said Cleric introduces himself as a paladin the NPC would hate him the same unless the NPC has metaphysical awareness.
If you are playing a "paladin," you will have unique abilities that only the paladin class has. Those impact how you play your PC and how NPCs perceive you when you use those abilities.
