Lomed Mkol Adam-
Lev Tov and Ayin Tov are good by definition; this what the Mishna in Pirkei Avos means to imply.
I disagree.
Shechting an animal definitely causes it significant pain.
I am sorry to hear that.
However, since the Torah allows one to eat meat and it is even a mitzva sometimes, I do not believe that this pain caused to the animal is morally wrong.
Unless you will tell me ???? ???? ???? ??? ???, in which case I will not have a response. The only thing is, from my understanding of the concept of morals, which is basically moral relativism from a natural, human standpoint, I do not need to accept any such docheik with regard to why we may eat animals, and therefore I will continue to assume that there is absolutely nothing wrong with killing animals in order to eat them.
