Philosophical babble on human error.

So, a disgusting person made an article called "1001 ways to torture a cat." I made a massive reply.
But he will probably never approve the comment. So I made this comment- uhh... novel, on human error.
It all started when he listed disgusting methods(microwaving cats to death), leading me to have a mental uproar.
"This is sick. It is perfectly normal to hate cats.
You have a right to.
But what kind of psychotic person would do this? Inhumane acts of torture to induce pain.
Worse yet, there are people who find humor from this...
What species... WHAT SPECIES ENJOYS TORTURING LIVING THINGS OTHER THAN THE DISGUSTING HOMO SAPIENS? Do wolves or panthers enjoy killing their prey? NO! They do it for survival! Humans on the other hand... I just don't believe us people. Even pet owners who have owned mammals should understand other animals. Humans are mammals. Mammals have feelings! This isn't a fish, insect or bacterial fungi, THIS CAT/DOG/WOLF/TIGER IS FROM THE SAME ANIMAL CLASS AS YOU!
Human error. No living thing on the planet fights wars, commits inhumane atrocities, spends billions on weapons meant to "humanely" kill other humans, other than your own homo sapiens.
Why are we humans so evil?
From the moment we exit our mothers' vaginas we have the potential to either be great sinners or great men/women. By sinners I don't mean in religion. I mean sinners of the human sense. The human conscience that has deteriorated in most of us.
Why spread the human error to ones other than us?
I'm off to write a philosophy book.
I disapprove."
