You and I are stranded in a mountain pass in the dead of Winter.  You can make it the Donner Pass if you like.  We are starving to death.  I catch Pneumonia and die.  Do you eat my body?  I'm a big old dude and would probably keep  you alive through the Winter.
     If the situation was reversed would you want me to eat you? 
     I would absolutely give you permission to eat me if I died.  Why wouldn't I?  And though I would be sorry you died I'd consume your body without reservation.  Once you die you're just another Mammal carcass. I would eat your body whether or not you gave me permission.  It's not like you'd know anyway. 
    So how do you feel about that?  Would you eat human flesh if your only other choice was starving to death?  I'd like to add that we're not talking about murdering someone to eat them.  That's a whole other level and topic.  But if your partner died on his own, would you?

If I've got some sriracha in my pack then there are far worse things I would end up eating than human. Syömään!

Long pig  mmmm
