That doesn't justify it. At our point in evolution we can make conscious decisions about what we kill. If we find it wrong to kill humans then what makes us more important than other animals. What would the purpose even be to eat meat when we don't need it? To enjoy the flavor of food at the expense of another living being is horrible.
You had me up until 'another living being'. Plants are alive, as are fungi and bacteria, yet we consume them as well. At what point is something a living being that deserves to live? Everything humans eat was alive at some point, the exception being those strange incidences where people eat metal or plastic or what have you (and plastic is petroleum or bio-fuel based, so even it was alive at some point too). Where do we draw the line? Animal species? Multicellular species? Only those that are common to our lives, like livestock and pets? The answer is not to avoid killing, but to avoid suffering. We have thrived because of meat, and it has played a crucial role in our evolution by providing us with a rich source of calories and nutrients. We may not 'need' it with the rich variety of plant foods available to us now thanks mostly to the exchange of crop foods, but eating meat, be it beef, fish, or insects, is certainly a normal part of the human diet.
I consider a "being" to be some kind of animal. And yes meat is a normal part of our diet, however we no longer need it to survive. We can use other things to get the required substances that would usually come from meat.
Still, one cannot expect all people to follow the same code or to share the same definitions. The best you can do, personally, is to raise awareness and organize against practices like that, and to not purchase meat that comes from such places should you chose to consume it. Another option would be to raise any meat you do consume on your own, or through someone trustwrothy. Being a vegan is an expensive and exacting proposition, and it isn't the proper choice for even a large minority of people. In many cases, the consumption of meat is cheaper than the consumption of fruit and vegetables, and economics drives many people to eat more meat than they otherwise might because of that.
