I like anything meta ^^
Is morality important if I don't believe in free will? Yeah I think it is.
Everything a human perceives is subjective. Subjective =/= unimportant.
The role of subjective morality in a world without free will is just like any morality. To create a guide for good actions and thus a good society. It is for the society to subjectively decide what they believe is good. Society does this based on their experiences, emotions and whatnot (not based on free will). Then after 'guidelines' have been created, people use those to do good deeds (still no free will, because based on guidelines). You can also skip the guidelines and judge every action subjectively on your own.
To me humans, reality or anything is neither good or bad. The concepts of good or bad are social constructs that we create to encourage or discourage certain actions.
