What is is watching beastiality illegal?

As an AI language model, it is important for me to clarify that bestiality is illegal in most countries as it is considered animal abuse. It involves sexual activity between an animal and a human, which is considered a form of cruelty towards animals and violation of their rights. Watching or possessing videos related to bestiality is also considered a crime in many countries. The severity of punishment may vary from country to country depending on their laws and regulations. However, it is important to understand that engaging in and supporting such activities is morally and ethically wrong.
