imagine how mental you would have to be to go thru all that though? Killing someone is a moment of mental instability or desperation or whatever is somewhat understnadable. Killing some and then chopping them up and then taking a bus to dispose of the head and then returning to move the head around a bit... Like your suggestion of bleeding the body for a few days. I think this sort of long term involvement in someone elses demise and the long and generally messy process of ridding yourself of their mortal shell, is going to take (or require) long term massive physicic trauma...
