Your friend is dead? And you're in critical health? Anything for the company, right? Eat your friend, nobody has to know 
I would attempt to make this myself, but I haven't found the time to be able to recently, but I think it's a funny idea that deserves to exist.
My original plan was to have a "Hold E/F" to eat, with no animation, just an instant health gain with a chewing/crunching sound effect, then the body disappears.
