What do Christians believe about morality and where it came from

Looking for answers from all denominations of Christianity. Morality. Did God create a universal law of good and evil and humans have the freedom to choose good from bad. Did God create humans inherently good according to his universal law of morality? Therefore when sin is committed it goes against man and God? Is man responsible for his own idea of good and evil, therefore it becomes shaped by humanities developement and the overall acceptance by society about what is good and bad. Or are humans inherently bad natured and we have to choose good based on a universal law of morality. Or am I just overcomplicating this idea? I've had this conversation with lots of peers. I will admit I dont know too much on where the bible stands on this issue. And I am hopeful to hear what answers come from this.
