Law vs Good

The versus bit of the tag title does not need to be taken literally. It could be simply recurring choice for the player, or recurring dilemma in the plot, where player or some central characters must choose between what law demands and what is actually good.

This theme can expand to loyalty vs good as well, where a soldier, knight, or such is following their ruler's commands which when they were given seem to be for the good, encounters a dilemma where actually not going through with those orders would do good.

This can easily backfire when the good option actually brings problems which the laws were there to prevent.
