I think we aren't thinking about this logically enough.
What do humans need most to survive? Water. What is the massive 7litre source of liquid near you? Blood. While a human can survive for a surprisingly long time without food, without water he/she dies in about 3 days. Therefore over the meat more important is the Blood.
Also, Blood is the right concentration (while water is too dilute that's why you get dialysis machines etc.) and is bursting with nutrients, each one that your body wants and needs. The Blood of your friend would let you live longer and provide your body with the nutrients you need.
Therefore I wouldn't mind someone eating my body because it is going to rot anyway and as long as they leave my bones intact (so my body will be exactly the same as though I had rotted naturally) and I would refrain from eating the meat of the other person but I would drink their Blood. Truly in this instance, the Blood IS the Life
On the other hand, what is a few more days? A few days either way makes little difference, unless it gives me time to get saved from this place of foodlessness.
As a side note: I am religious (Catholic) and I am for all the pro-life etc. things however I don't mind discussions like these, I think they're great. Too often these days people simply don't think about "what if....?" and live life as if they were forced into a routine. I like questions and discussions and do not mind someone disagreeing with me. While my religion does have a resurrection of the body aspect it is more akin to being given a new body, better than the one before. So whether bones, dust or in someone's belly it makes little difference.
Also, I will end up in my 10xgrand-children's food as I will rot, be ingested by worms and then turn to soil where plants will grow (you can see where those will end up). So whether eaten by worms or humans makes little difference to me really. Have a meal on me
