I've had more trouble with DMs who go crazy at the concept of paladin players. Yes, LG paladins should be against torture. Really, so should most LG, CG, and NG of any class. Same goes for theft and the like. Maybe not quite as stringent, but in general.
But give a DM a paladin character and it's like they immediately see it as a goal to make them fall, or to assign new strictures that aren't in the Code, or to somehow interpret the rules as if they were doped up on Nyquil during a religious epiphany. "And then the Great Prophet Gygax did descend from my showerhead and impart the wisdom within me via his stinging cold spray...."
I've been around some decent paladins in play. One guy had a decent 2e paladin, a little weak in melee but all around solid. Another had a nearly-decrepit 80yro paldin in Taladas who acted more demented than he really was so people would underestimate him (ala Shinjo). But most of the time, the DMs get wiggy at some point and start telling the paladin how they 'should' be playing them, when usually the cleric has been far more frivolous in respecting their deity's laws.
