Many choose Good alignments, because they want to see themselves as a heroic protagonist.
They then start torturing and murdering people, relying on 'justifications' as to why this is 'morally good' (justifications that make sense in their own minds).
I have heard of this. Seems sad a table would dissolve into that.
How common is the phenomenon of players asserting that torture is good?
And given that we're talking about game play and not just dinner table debate, what sorts of situations are arising in games that even put this onto the table?
Stealing bread and fruit to not starve is absolutely not a negative moral action, and any system that supposed that it is, is objectively and egregiously wrong.
Theft to survive is not evil. He was an otherwise good person, who didnt harm/ rape/ torture/ murder others, and was kind and altruistic.
If he was stealing for himself, pleasure or for wealth, then sure. If he's forced to steal to eat and is just taking what he needs to survive what society has done to him, then I don't see it as intent to harm.
In real life, systems of private property produce consequences that are objects of controversy. And the moral analysis of them is contested: for instance, Thomas Aquinas argues that there is a sense in which stealing for survival is not
really theft because the goods that are taken don't
really belong to their owner, because the only justified property claims are those that don't contradict the purpose of having material goods in the first place, which is (according to Aquinas) to satisfy human needs. Obviously there are many libertarians (eg Robert Nozick) who don't agree.
In the fantasy context, though, it seems incumbent on a table which wants to avoid real-life controversy to frame things in such a way that those controversies don't arise. Eg Robin Hood robs from the rich to give to the poor, but the background context of the story (at least in its Errol Flynn version) is that the poor are only poor because of oppressive taxation, and that systems of nobility and honourable leadership (eg by King Richard) are possible
without oppressive taxation, and hence the need for robbery to ensure justice is only a temporary need resulting from King John and his underling's evilly perturbing what is, in its underlying structure and operation, a fair social system.
I've never seen a Disney version of Aladdin, but I am going to guess that it's presentation of economic justice and oppression is similar to Robin Hood.
If we are talking about the contribution of the alignment system to RPG play, we have to consider what sorts of questions the fiction gives rise to. If you want to run a game where overthrowing the feudal order and replacing it with a cooperative of small land-holders is a serious object of consideration, then I think the alignment system will just get in the way, given that it presupposes (for instance) that feudal rulers of lands like Cormyr (sp? I'm not a FR buff) and Furyondy can be LG paladins.
