Middle Path:
“even people who don’t believe in G-d can be moral, have values”
Being “moral” only because you have decided that it is the right thing to do is worth nothing. If one does not believe in God, they have no chelek in Olam Habba. Nadda, nothing, zilch. Any “good” that they do in their lives is worthless. This is because the only point in being a good person is to listen to Hashem and emulate Him, and thereby grow closer to Him. If one is trying to be a good person for any other reason, there is no point. So yes, an apikores can be “moral” and they can have “values”, depending on how you define the terms, but it simply isn’t worth anything.
