This is a very good question which should be asked of anything mytho-poetic.
This question has been asked of the Bible for more than 150 years, leading to a benign form of Chrisianity. However this question has not been asked of the Koran, and we can see the violent results every day in our newspapers.
And just as each one of us is subject to questions of right and wrong, so the mytho-poetic is also suject to questions of right and wrong. And it is right to ask these questions and wrong not to.
