If it feels pain...

I just read something that I found horrific. I was reading the website for my favorite news channel, CNN. I found this. It seems that crabs actually feel pain.

How can we destroy these precious little bundles of joy, especially knowing that they feel pain? How could any human being willingly inflict pain on something so small. Something that never hurt anyone. Inflicting pain only for their own convenience, slaughtering millions of the little fellas.

I don't understand it. People can be so mean.
