Well their vile creatures if that's what you mean. Ever seen their victims? They basically chew off fingers and noses.
Yes, dogs seem to like processed and cooked food. At least the ones I've had.
Most of them I would think, are savage killers. I know hyenas cannibalize one another when they're young, allowing only a few to mature. All animals are quite brutal, in fact, even to their own kind. But I think grey parrots have the larges language capacity.
What things? The Bible tells us we're brute savages in our flesh. It compares us to animals (beasts) when our depravity takes over. But we have a conscience in us to fight this which is something animals lack.
You see, it's not our animalistic behaviors that make us human—rape, murder, etc. Those things all animals have. Our resistance of our brute instincts is what makes us human. Chimps are perhaps the most vile in this area. I'd consider them much less human in appearance that other animals.
