Brother:
I am surprised at your response but you certainly are entitled to it. Didn't the news story mention that many went after to drink alcohol. Those who attended did not go for the meat. They would be gone before that many animals could be butchered, furthermore most of the animals would begin to rot before they could be. I also have doubts that anyone will eat the birds and such animals.
What kind of Goddess would be pleased at this. I think the thought of personal sacrifice has gone horribly wrong.

to be honest I read about this a while back and did not read this exact article. Animal sacrifice has long existed in Hinduism. Whether the goddess wants it, I don't know. What I know is that People of any religion convince themselves that this is what their god wants whether its right or not. e.g. Aghorees who are mainly followers of Shiva use human skulls for black magic. Not only that, many times are they caught grave robbing. Do i think its right? No. Do they think its right? Yes. Do people pay them for the use of the souls of those skulls? Yes. In the end its all a business. The meat in this sacrifice is probably not wasted. Nepalis probably have a big feast at the Indians expense.
Looking throughout the world, all Islamic meat is a sacrifice to Allah no matter what they say. Infact, There was a video on this site where a goat is sacrificed at Hazoor Sahib? for the Tilak. Whether its used for Tilak or for offering, point is an animal is killed.
I don't really know why they would kill for the Goddess. Plus this is Nepal I have no idea about their traditions. What I do know is that in India atleast in the pilgrimage towns of Durga or 'Sheranwali Mata' in Punjabi, the goats etc are "donated" but not sacrificed. they are left to roam. I had the unfortunate experience of being headbutted by a young male goat who had been left to roam in Chint Purni in Himachal. No one eats them because they're an offering to the goddess.
The only hindu goddesses who I know of in terms of sacrifice is Kali. It is the belief of Kali worshippers that Kali wants blood so they give it to her.
