You can call us robots, something similar to what singularity would achieve in case of Artficial Intelligence. The thing is we are constantly expanding out knowledge set (through experiences of our own or knowing about experiences of others or fictional work of many authors, the information set keeps expanding for humans). Free will is nothing but how we act under different circumstances, whatever our human code throws out. While I haven't looked at the spiritual angle, I think the spiritual or miraculous experiences we have are again mostly (and again mostly) outcomes of codes thrown out by the brains of other living beings. and yeah i don't think the life is completely written. Because experience aren't written. It is all pretty much a simulation though of very random scenarios.

emotions are often tricky. they can be outcomes in most cases as far as I am concerned. Outcome is a combination of physical and emotional reaction. That's what I think.
