I love animals but I love eating them too so I have no issues with them being killed for eating. Seen my grandmother kill a chicken in front of me, played with a turkey before it was dinner and seen my dad skin a bunny.
I think the issue here is that it was killed in a public park. That's a bit too messed up even for me. Pore sheepy Bah
Also, it doesn't seem to have been slaughtered for food but instead was killed as part of a superstitious ritual sacrifice for "luck". On the plus side, at least they didn't use one of those rare virgins that are in such scarce supply these days.
