As for any examples of bulling or killing for pleasure among the animals from what I've read for the most part that occurs when the animals are living in stressful conditions caused by their proximity to and/or mistreatment by people. Also, a degree of self-identification with the behavior can occur meaning we can "read" into the animal's behavior what we see in ourselves. We cannot read the animal's mind though.
I would suggest reading more, then. It happens without those conditions. As to reading animals minds, no one was suggesting that. It's observed behavior. We are animals and share a large set of the same behavior as them.
Surely you're not saying we are the only ones on earth with large brains and opposable thumbs. We're not.
So, did I say that? If I didn't, I find it curious why you would bring up something I never said and then argue against it. It seems quite pointless.
