These debates have been going on for a long time and basically everyone that eats meat disagrees and everyone that doesn't agrees hahaha. Yes we are human and thus bias.
The very simple truth to answer this question that no it is obviously not wrong or unethical to eat meat or kill an animal. What is VERY unethical and wrong is the gross and unconscionable ways humans FARM animals and the GREAT disrespect that their lives, dead or alive are treated.
