Some are morally permissive I would say. Here is why: let's say you grow up not knowing stealing is wrong and you steal one day, but don't know it--> you didn't do an immoral act.
Stealing is still morally wrong, no matter what you think about it, that is founded in human nature. By stealing you have commited an immoral act. However, you are not culpable for that action because you had an invincibly erroneous conscience, so it is not a sin. It is still immoral, but you are not personally culpable. Therefore, the Commandments state basic facts of things that inherently bad for humans. The things that the commandments prohibit are not suggestively prohibited. Here is an example why.
Physically, some things are good for me to eat, and some things I should not eat. NO MATTER WHAT I THINK ABOUT IT, it is still never good for me to eat a bowling ball. Again, no matter what I think about it, it is good for me to eat vegetables as long as I am not allergic to them or something like that.
It is the same thing for spiritual matters. Some things are inherently good for me as a human, some things are not good for my soul. God, in the Commandments, lays out our human nature before us and shows us that doing these things is inherently bad for us. Not obeying the commandments is sinful, therefore.
