I think one can argue simultaneously that there are absolute moral principles and at the same time argue that it is impossible that all people in all states of affairs, will always observe (or be able to ) them. I think the existence of evil is what allows one to argue as such. Consider the poor individual who steals to feed her family. One can reasonably argue that an absolute principle against stealing exists (say in the mind of God, unless one argues that He is subject to the same principle...which creates a further problem) and at the same time argue that she was not justified and yet she had almost no other choice due to the evil state of affairs that obtains for her. Again, her stealing is contingent on an evil state of affairs that exists prior to her activity. Consider the state of affairs where everyone with excess gives to those who lack, do not consume more than needed, etc. Even better, consider the state of affairs in which everyone observes all moral absolutes, all of the time. Then, it would seem examples like the one given (a woman is compelled to steal ) would not occur. My main point is that moral absolutes can exist, while at the same time they can be impossible to fully fulfill because of one's enviroment (one in which evil exists). Her conditions do not justify her, they only show the extent that evil affects human society and those who live in it.
