The idea of ​​goodness and moral laws

Hello Rabbi,
I wanted to hear your opinion on this:
In my opinion, we have a distinction between the concepts of good and evil, but without a distinction in moral laws – it is forbidden to do evil. This means that there is a kind of "idea" that shows what good and evil things are. But it is not a commandment that evil is indeed forbidden to do.
If what I said is true, then your words in the fourth notebook that you mentioned about the need for a moral legislator will be dropped.
Does the Rabbi think this is true?
Also, I wanted to ask the Rabbi,
It is often claimed that bad things are not inherently bad, but are merely the absence of good. In general, our entire understanding of what is bad is merely the absence of good. (A kind of black versus white).
Does the Rabbi accept these things? Understand them? If so, I would be happy if he could explain. Because I am pretty sure that killing an innocent person is actually a bad act, not just "the absence of good."
