" I think animal abuse is wrong, because it hurts animals" --- If you follow your beliefs you should become a vegan

" I think animal abuse is wrong, because it hurts animals, i do not like people nor animals being tortured...."

Most people would agree with the proposition that it’s wrong to inflict unnecessary suffering and death on animals. We could have an interesting philosophical discussion about what 'necessity' means but the reality is if it means anything, if it means anything at all, it means we can’t justify suffering and death for reasons of pleasure, amusement or convenience.

"The problem is that eating animals and animal products is, as a matter of moral analysis, no different from dog fighting. We kill and eat more than 57 billion animals a year, not counting fish and other aquatic animals, which involves probably another trillion animals at the least. A billion is one thousand million. A trillion is one million million. So every year, we are responsible for a staggering number of deaths. No one doubts that using animals for food results in significant suffering under the best of circumstances and, as a necessary matter, the killing of the animals. Although many of us think that the dairy and egg industries do not involve killing animals, that is, as we will see in more detail later, incorrect. So let’s apply the analysis that we all agreed was uncontroversial to using animals for food: have we got a good reason? Is there any necessity involved? The short answer: no."

You are trying to justify human behaviour by looking at nature when you apply the food chain-argument. In nature you will also find cannibalism, rape and plenty of behaviours that we humans are considering are unethical. I write some more about this argument here: http://bloganders.blogspot.no/2013/04/vegan-answer-to-humans-are-at-top-of.html
My comment will be too length if I should address everything that you wrote, so lets start with this.

 "A lot of other people, or even animals if they had the chance, would not be as compationate. "

Not strange at all since we live in in a completely extreme world, a world in which we sacrifice our love and compassion for animals on our plates for palatable pleasure/convenience.

What is extreme is thinking that it is morally acceptable to inflict suffering and death on other sentient creatures simply because we enjoy the taste of animal products.

What is extreme is that we say we care about animals and we believe that they are members of the moral community, but we sponsor, support, encourage and promote “happy” meat/ dairy labeling schemes.

What is extreme what we encourage our children to love animals at the same time that we teach them those whom they love can also be those whom they harm. We teach our children that loving others is consistent with hurting them. That is truly extreme— and very sad.
