I think you can have this same dilemma as an atheist as well. I’m personally agnostic as I don’t have the knowledge to make a decision.

If we are all just atoms moving/reacting, surely everything we’d ever do would be predetermined by the initial reactions/vectors/forces at the big bang. I know there’s quantum randomness and stuff, but it’s possible that’s all calculable and we simply don’t have the means to calculate it. If that’s the case, IMO we still have freewill because we can’t predict the future, and it’s still worthwhile to move forward doing our best to be good people.

Thanks to your question, I learned something new today.
