Food for thought- or Enjoy Seafood?

I've been thinking a lot lately about the way they harvest Crab Legs for our eating pleasure and have come to the conclussion that I do not wish to mess up in this lifetime and be re-born as a Crab. Though, I have friends and family members that may already tell you I am living said life now.
Crabs regenerate their limbs. Harvested crabs live in tanks and get their claws chopped regularly to send to various seafood restaurants and personal kitchens to feed the glutinous (for in this day most people cannot be said to be starving, especially when they are crab consumers). These crabs are not given any heavy barbituates, tranquilizers, or hallucinogens FDA approved or otherwise; they are left to regenerate and then harvested again until they die of misery and pain.
I ask you, why not eat the entire crab? Why be greedy and take just the good stuff and let the miserable crustacean create claws for us to consume later? Could there not be a connection between eating food that is raised in misery and humanity's deeper plunge into collective self disgust? I don't care if the claws are organic or doped to the gills (if crabs even have gills- we should be eating those too) just don't torture them before eating them to appease the overindulgence of the mass.
