thats a really good point. i used that as an argument to myself to not eat meat: "i wouldnt kill it myself, so why am i okay with someone else doing it for me?". but i agree that that really just depends on what enivornment you have been accustomed to.
my line of reasoning at this point is basically: i do not need to eat meat, i prefer animals not to die or suffer, making and eating meat is a process of animals dying and suffering, so why eat meat?
Well, you can turn that around 180 too.
Animals DO suffer. They pretty much exist to survive as long as they can, only to be ravaged by another animal.
Think of your favourite animals and how they most often die. Chances are they're killed aka murdered by the next big fish in their eco-system. Ripped apart by teeth probably. That can't be considered humane, and yet it's natural.
Best to just put it out of mind I guess....
