"If I Ate Lab-Grown Human Tissue or Organs, Would I Be Considered a Cannibal?"

I'm adding this to my list of moral questions about things nobody wants to do.

Questions:

1. What else can we put on that list?

2. If you bite your cuticles or the inside of your mouth and keep chewing and swallowing, are you a cannibal?

3. Why does it matter whether a particular word — such as "cannibal" — applies to something, when the real question is whether something is right or wrong?
