Bad take. The problem here is that the person feels nothing seeing a human being murdered, only when it's a cat does it become a problem.

It's the same type of person who thinks you may never portray rape in film, because that is personally detestable to them- murder people and torture them and it's entertainment, but when it comes to their pet outrage (no pun intended) they are incapable of abstracting the thing because of their specific personal mores.
