If you ever do find yourself in a similar situation, where your friend is begging to be killed, try to remember the case of David and Raffi. These two best friends went on an overnight camping trip in New Mexico. They got lost, dehydrated, and ate unripened cactus fruit to survive. David was in agony and begged Raffi to kill him. Raffi stabbed his friend twice with a knife. Then he exhausted himself covering David with heavy rocks so the buzzards wouldn't get at him. Luckily a ranger found Raffi still alive on day four.
Prosecutors charged Raffi with murder. There were some odd things about Raffi's story. For example, why did he exhaust himself moving rocks instead of trying to find his way out? He was found only a couple hundred feet from the trail. I guess jurors partially bought Raffi's account of a mercy killing. He was found guilty of second-degree murder and given a light sentence.
The problem is that once you get severely dehydrated, you stop thinking straight and do odd things, like forget where the trail was in relation to your campsite, or worry about the buzzards getting to your dead friend and start piling rocks on top of him. You lose focus and don't make good use of your remaining energy. Everything you thought you would do in such a situation goes out the window, because you aren't in your right mind. You don't think you could ever kill your best friend? Well, you've probably never been severely dehydrated with him screaming for mercy under the scorching sun in the middle of the desert.
