Arkhandus said:Also, alignment shouldn't be changed from just one event. Unless it's a really drastic event, like destroying an orphanage, or betraying one's evil master to save the world from his maniacal plot, or......um, whatever Lawful or Chaotic acts would be appropriately significant as to change a character's alignment suddenly.
Agreed and therein possibly lies the difficulty you're having with alignment at the moment. One act alone does not suddenly turn a character evil, especially when their original alignment was lawful neutral, which can be argued to be the alignment that says "I do what I must to protect others." If the character believed that he was justified in using torture to obtain information that would help others and didn't seem to be enjoying the process (plus the target was incredibly stubborn and standard interogation tactics weren't working), then it seems a sudden jump to move to an evil character.
The problem with such an alignment change is that it does have a minor impact on the game. If a character in the party casts detect evil, then this guy'll light up. Protection from evil will actually hinder the character and prevent him from working with the party in battle. Not huge things, no, but an effect nonetheless. Maybe if the character was allowed to keep his original alignment but others will treat him as if he were evil, someting like how dwarves are perceived by others races in some games (specifically 1E D&D with Charisma modifiers for other race characters). If he wants to remove this stigma against him, he'll have to do something remarkably good to put him back in good standing with others. So he doesn't show up as evil to a spell, but still feels the heat for his actions.
