Bites and feeding... Its all in the presentation. If the material is presented in a educational and scientific manner such as a documentary of the animal in its natural setting I would say it is fine. When the material is presented for entertainment purposes only it reeks of the old school Roman arena where they slaughtered animals purely for the entertainment of the audience. Animals are slaughtered for our own consumption every day however only a warped individual would make videos of it so that other warped individuals can be entertained by the carnage. On another note, take it from someone in the tech industry, Facebook and products like it are not your friend. The information is used for purposes that you may have not even considered. Keep your life as private as possible.
