Sure. I'm not saying these things can't come up in many different styles of play. What I'm saying is there is a difference of frequency and consequence. There are games and playstyles where challenges to your character's sense of honour or paladinhood are the primary focus of play, or where the outcome of those challenges are likely to be profound and far reaching - either real collateral damage to oneself or one's goals and loved ones for sticking to the code, or an abandonment or breach of the code that leads to a significant change in status quo for the character - exile, ronin, death, and so on.That's perhaps true but it doesn't need to be. I played a Paladin in a recent 1st Ed Pathfinder campaign that routinely visited brothels between adventures (which was totally legal in the setting). The GM acting through the NPCs Mayor of the town and head of the local church that he followed, constantly challenged him on it, saying it was bringing the church into disrepute, not behaviour fitting of a paladin. It allowed my Paladin to have a religious debate with him. At no point did the DM go "This isn't Lawful Good, you loose your Paladin status", but it was challenged in character.
