I find it funny when some (rare) vegetarians argues that eating meat is animal cruelty, but what's the difference between an animal and a plant? aren't they both living beings? for me if it is for the sake of eating then it is justified, nature was created in such a way that there are ecosystems and as such there are cycles on where things feed on other things, and the same goes for us human, when we die worms and plants feed on us and the cycle continues.

Now killing animals for fun that's another story and shouldn't be allowed.
