What’s wrong and what’s right is in your qalb. If you don’t have it, it doesn’t matter. You would just be a hypocrite and not a real believer. At the end of the day life is about choices and no divine being is going to make those for you. You will decide and you will be judged accordingly. In this life and the next. Choose wisely. As you grow up, you will have to make a lot of choices and then you will understand. How could you possibly know now? What hard choices do you make? What clothes to wear to school tomorrow?
You keep mixing up morality with free will. Yes, we have free will and will be judge accordingly.
However morality isn’t in our qalb because if it was then all humans would have the same morals.
