We can't control every animal out there, that's right. BUT! That's only because they don't have the brain capacity that we do! We can do the right thing and eat alternatives to meat, they don't know the difference, they're raised that way..
And ah, sweety.. Disney is cartoon..
Killing animals is definitly murder because there are so many alternatives to iron and protein such as beans, nuts, eggs, spinach etc... Killing animals is not nessicary.
