If the being known as Ned on this forum is made up of atoms that amount to what we consider a "good person" then that person will make good decisions and behave as a good person would regardless of whether they have a real choice in the matter.
I maintain agnosticism as my belief system, but a book called Many Lives, Many Masters was helpful to me. The concept that we are here to gain wisdom and that this life is about learning is comforting and strangely makes a lot of sense. And the concept works in a simulated multiverse with people under the illusion that they have free will.
