I've seen much worse than that before, but I was just taking others into consideration. A couple of people on this forum told me that the video bothered them so I was giving my opinion about at least warning about the graphic content of the vid. Idk why your demeanor in this forum is turning into that of a cocky person, but thats not for me to judge, thats your choice on how you want to act. however, it seems that nowadays anything I post is either "hater attitude" or cockyness. I will just say that if you want to be respected, you have to respect back.
And to answer your question, yes it is cruel. There are so many types of injustices done to animals, and only because countries fail to implement any laws that protect animals. In a cruel way it makes sense, considering that in certain caste societies, lower class people are worth the same as an animal. In my own personal scenario, I lived in an area where there was a large majority of stray dogs. To compensate for it, a lot of them were killed. My grandma used to kill girl puppies because she said that was the only way to reduce any newborns from being born. In my opinion this is way worse because an animal is being killed just for the heck of it.
