Replace "Killing Joe", with say "not giving Joe a million dollars" in that argument, what changes?
What changes is that I would like to have a million dollars as much as Joe would. Similarly, if I had to trade between Joe's desire to live and my own, the latter would win.
In another comment you claim that I do not believe my own argument. This is false. I know this because if we suppose that Joe would like to be killed, and Joe's friends would not be said if he died, then I am okay with Joe's death. So there is no other hidden factor that moves me.
I'm not sure what the observation that I do not give all of my money away to charity has to do with anything.
