The standards to which Rich holds his paladins before they Fall (at least in the comic) is such that im not sure much meaningful connection can be made between them and actual D&D paladins. the idea of "technically Lawful Good" is very much a metagame concept that cant really coherently apply in a narrative-driven story that lacks players and other external judges of character who are willing to shrug and move on due to not caring enough to start a fight with real people over imaginary orcs.
It is, at best, very much a square peg and round hole issue.
