You are in more level headed and informative side of animals and your choice. This was something I was also  going by as a small town kid.

But later on when I've read more about animal rights and animals self-worth without being tools to us, I came to conclusion that I do not and shouldnt have a decision over someone's life. Every animal should live species typical life and make choices for their life. As we do not need animal products in our food killing animals just isn't justifiable for me, otherwise why wouldn't I just kill anyone for my own convenience? 

What are you thinking about these thoughts?

Well, tbf, morals get really funny. For example Muslims do believe that everyone that doesn't practice Islam is an infidel and can be treated like crap. According to their morality that is fine. To someone that isn't Islamic, thinks it's a load of crap. Who is right? Also why? Indians worship cows. As such the cows are allowed to wonder wherever they want. Most of them are diseased. Is it moral to allow a diseased animal to wander around suffering because you think it's a God? Or that it's fine because the animal has freedom of choice? Humans are omnivores. Always have been. While a lot of vegetarians and vegans firmly believe that the human body does not need meat to survive, we really do. While yes we can get protein from beans and other plants. It is not the same muscle building protein that animal muscle provides. I'm sure that we could find scientific studies that would prove both of us right. Which one do we believe? Why? You mentioned just killing someone for your own convenience. While I hate to answer a question with another, why don't you? What actually stops you? Is it because you can empathize with the victim and the victim's family and wouldn't want it to happen to you or someone you know? Or is it fear of punishment? Being prison or how people would treat you. One needs to be very careful about morals.
