>I'm not quite tracking what you mean by 'shared computation' I think they are trying to say that depending on where you believe the determination for will occurs, it might affect how much "blame" you place on someone performing wrong actions. If you believe they gathered external information and made an internal calculation to perform an action themselves, you might call that free will even if the final decision to act was affected by the external factors. On the other end of the spectrum, I believe they were trying to say if you argue that an individual's computation of external information is not a free will action, then you must zoom out and incorporate the externalities which determined that individual computation/resulting action to start to discuss blame. This would essentially make the "free will computation" a shared computation in that deterministic externalities combine to remove individual free will and impose a sort of "cosmic will" where you blame the cosmic will for your bad actions, and try to excuse yourself as a result. I believe this is what they meant by "as a result it becomes possible to justify horrible actions."
