"Killing is OK but torturing is not"
From the above statement I would like to point out how we treat ourselves, the human beings. We think that death sentence is okay but torturing ourselves to death is not. In that case, i can guess what answer would animals come up with.

Basically, you have absolutely no right to question some one's intelligence. I may not be as intelligent as you are, but that doesn't mean that you should mock me in public. :-/
