Dostoievski once had a character imagine what a head would think if for some seconds it were aware of having been cut off by an executioner's guillotine, or if somehow it were aware for a full minute, or even for five minutes.
I should think such a head would think thoughts entirely dependent on the circumstances and that the type of blade that committed the murder wouldn't affect the thoughts too greatly.
I loved you, it might think, thinking of its loved ones. I did well there, if might think, thinking of its accomplishments. I'm sorry, it might think, dwelling momentarily on its deepest regrets -- as likely as not relatively trivial incidents in which the head together with its body had hurt someone's feelings.
I've died in a war, the head might think, despite opposing wars. I took the risk and enjoyed the thrill, yet the injustice remains. I didn't launch the war. I didn't make millions off it. I didn't win votes from it. I tried to tell people what it was, and here I am no better than a soccer ball about to cease existing as a consciousness.
