As others have said, this is more a good vs evil situation than code vs alignment.So to start with I don't like Paladin PCs. Did not like them in 1Eor 3E, 5E is a little better but they still have that silly oath. They are great for that knucklehead NPC.
We have an oath of devotion Paladin in a game I am DM ing. His Deity is Tyr. He is Lawful good, the rest of the party is Chaotic (CN fighter, CG warlock/rogue and CN Barbarian). As an aside I am not a fan of CN players either but that is another topic.
Well there is constantly friction in the party as to how to handle things. For example they typically want to kill prisoners after interogating and promising to let them go, they have no problem lying and well acting Chaotic. The Paladin tries to role play his character with his oath but it is causing a lot of friction. It came to a head in the last game when they let a stone Giant go after they got done arguing with him. The two CN characters wanted to kill him because they thought he would come back and attack them. the Paladin stood his ground and said no way and drew a line in the sand, the CG warlock rogue sided with the Palidin but would have been fine with "looking the other way" if the Paladin did not make a big deal out of it. OF course they were ambushed by said giant and friends later that session. It could have been a TPK, and would have but I played the Giants poorly in battle, making some bad decisions and the party scraped out of it (barely).
I am really having trouble with this because I think in real life those characters would just part ways - the Paladin can't accept such behavior and the others can't stand the goody-goody Paladin. Of course in the real world parting ways means an end to our game. If it wasn't for his oath I think he would just relent and basically look at alignment as a guideline or belief instead of a code to live by.
My suggestion would be to ditch alignment and the paladin's code altogether if it makes your games run smoother. Let the character be a follower of Tyr and live by the tenets of Tyr, or even ditch that if you’d prefer. As a matter of fact, a religious fanatic is likely to be more problematic than someone with a romantic knight code of honour.
No alignment, code, or deity should be a pass to legitimize disrupting roleplay or allow a player to be a « dick ». Sometimes character personalities will clash. That’s cool, it’s part of the game. Just don’t let two letters on the character sheets dictate and justify when these clashes happen.
Talk to the players about it. Propose your suggestions. Ear out theirs. Communally come with a solution, and keep on dungeonnin'!
