I sometimes feel that free will has a stronger connection to emotions than reason.
SPLURG! ...... I just threw up lol, jk. Depends on the emotion in my opinion. Jim's free will isn't that much different than an advanced psychobabble(the babble part being the mix of older theologics combined into it) approach I think. Where in negative consuming emotions come from the shadow and constitutes a process that happens to you, which you can then make a choice from, vs 'higher' emotions such as Love or Faith which constitutes a continuing choice to 'feel' such things.(Butters and how Murphy tells him to make a choice before he becomes KotC is a
perfect example actually)
Bottom line to me, those higher emotions are connected to the superego/ source of creation and the negative ones from the shadow/subconscious. Which directly aligns with my theory on Nemesis and Lucifers old role.
