When a cannibal cuts off your right arm and right leg, and roasts it, and gets good vibes munching on your roasted right arm and right leg then you will understand his good vibe yummy pleasure in roasting and eating your right arm and right leg.
When a cannibal puts an apple in your mouth Donquixote and roasts you over a spit, you can be happy because you will understand the good vibe they get from munching on you.
I know some hungry cannibals who have a spit ready to roast you for thier dinner, are you plump and juicy? Is your meat clean? Much grizzel or fat in you? Is your liver pink and clean? Are you succulent and juicy?
