Easier said than done. Identifying what exactly 'the right thing' is can be very difficult. In fact, sometimes it is only in retrospect that we can truly know that we have done 'the right thing'. This item seems to have been added with the idea that there is a good vs evil fight in the world, and that it is only a matter of choosing this golden idea of 'good' in ones mind which is important, and what comes after will be natural and pure. However, it is probable that as Aristotle argued, there is no such thing as a universal good, and that no matter what you choose, there will be some sort of inquiet and evil as a result.
In theory, it is probably a measure of good character, but in practice, it is much more complicated than this.
