Viewpoints haven't been proposed, at least not any I'd disagree with or that go outside of the framework of Mosaic laws, for example. Only additions ("why no rape? Include no raping!") that make sense and follow from/do not leave the same virtuous paradigm.
And saying that a death caused by self defense is not the same as violently going outside starting shit/killing people are not similar things just because someone died and that you'd have to be in a coma not to realize it is a pretty lukewarm take, lol.
And finally, saying some things are A and others are B, that truth exists regardless of our ability to get to it, and that not everything can change on the basis of our whims (right and wrong in every situation, for example, but it's beyond morality) is just an epistemological stance. Nothing about faith, or religion, just how you see the world.
And the Qur'an? You mentioned wanting something solid, something extensive and well written and I know that, besides the fact that I'm lazy and easily distracted and will probably never write anything, even if I did write something of quality on the topic, it would not be better than the Qur'an. I can't even write to the level of Ecclesiastes and that's just Solomon speaking from lived and analysed experience! That's another book recommendation, btw, it's in the Bible.
