2. But I should say my view of the Paladin has been tempered for years by RuneQuest which has for many religions positions of Priest and Rune Lord, the martial Champion of a God/Cult who is supported by the Cult to devote his/her life about seeking out its enemies and Defending its interests.
With this you are also able to have more complexity in "Alignment" where Gods and Faiths who look after their own people but view a Neighbour who does things differently as the epitome of Evil, and their is Divine proof of their assertions because their Champions get holy assistance when fighting the "evil" guys across the border.
I'm reluctant to demonstrate this with a real world example, and if it crosses lines I'm sorry. But the 2 political camps in the US seem to be an example, both want the Country to do well, but are completely at odds over how to do that, and appear to accuse the other of being totally corrupt and "evil". I am not stating any actual position with this statement, just describing an example of diametrically opposed but both non-Evil groups.
