I didn't watch it either, but I guess by your comments. I have watched few videos like that before. All these people doing cruel things to animal deserve for their sufferings and we the consumers buying the production from such cruelty will also have our own share of sufferings. Watching this video is difficult, but ignorance and turning blind eyes to cruel things happening around won't help either. Let's at least promise to ourself that we will be aware not to be part of such cruelty as much as possible:
:by consuming the eggs produced from cage-free chicken,
:buying meat from companies not known for animal-cruelty,
:by the least use of the products made from animal skins,
and so on.

“The greatness of a nation and its moral progress can be judged by the way its animals are treated”
Mahatma Gandhi

I think Gandhi is still right and this holds true for India and Nepal too.
