A question about choice, morality, and God

Hello, Your Honor, I have a question: For scientists, the first rule is of course not to set axioms about the universe. In the 19th century, they thought it was completely deterministic, "God doesn't play dice." Since then, there has been a revolution, and we see science becoming more and more sophisticated, and things that were unacceptable in the past are now proving to be absolutely true.

My question is: Do you think there can be a situation from a materialistic perspective, according to which a person does have a choice (real, not from a compatabilistic perspective), and there are objective moral values, at least very basic ones such as that killing an innocent person is never "good", or do these terms only apply to those who believe in God? I sometimes talk to atheists. Usually, most of them tell me that there really is no choice, and that morality is something that changes in society, and if I grow up in a society where killing is good, then I will probably think so… that overall it is an evolutionary justification and more… But I spoke today with an atheist (agnostic) who told me that from his point of view, a person can indeed have a choice even without a transcendent factor, and that there are things that are *objectively* bad or good.

Honestly, my first reaction was that he's not an atheist. At least that's how it seems to me, that it's impossible to talk about a real choice in the purest sense of the word, one that can be truly judged and said whether it's "good" or "bad" in a world that operates without any intelligence guiding it, and certainly in this case there's no such thing as "morality"! But I'm simply guilty of setting axioms about the universe and am very fixated on this concept.
What do you think? Thank you very much and have a good week.
