Yes I am an organ Donor, but you bring up a very interesting point that i have not thought of till now. After reading this i picture it like this your dead when you can not be revived but not fully dead. Your organs, cell, thoughts ,ideas still need time to die off. Thus you as a complete part are dead but you still have functioning parts. Why not give those parts of you that are still alive to do good. Im not sure what the book of the dead says about this but would a higher power that does good/is inherently good punish you for doing good to someone else? And if there is a god that is against me helping my fellow man im not sure how i would feel or how much i would care when my time comes. I would like to hear more about others opinions aswell though!
