Sounds like a Lawful Neutral Paladin to me. Whether that shifts him towards Unaligned or keeps him at Lawful Good is the subject of obvious debate. Lawful Neutral (inquisitor-style) isn't well represented in the current setup. But someone that values LAW and SOCIETY (Lawful Good) is likely to value Law over Life. I'd argue that the current Lawful Good alignment is often less good than Good.
I'd say he'd be better served as a Paladin of Erathis than Bahamut, but he's obviously already made that choice.
