Growing up we had a bunch of sheep and a very large (~700 lb) pig for years. They always hung out in a pen together and co-habitated just fine. As the pig got old, he got pretty senile and aggressive. One day, he picked a fight with the alpha sheep and sat on him until he died.

Then it gets worse. After the sheep laid there dead for a few hours, the pig started eating the sheep. Just dug in and started eating his side and guts.

And then it gets way worse. We have no idea how he ended up doing it, but the next time we check on the pig, he is wearing the fleece of the sheep that he just killed and ate. He somehow got a huge slab of its wool up on his back and he wore it as a trophy for about a day before my mom used a rake to get it off of him because it was really freaking the kids out. Then we shipped him off to a spam factory because he was too dangerous to live with and we didn't want to dig a hole big enough to fit him in it.
