I'm a carnivore. It would be rather hypocritical to condemn someone for shooting a deer and eating venison while I'm chowing down on a big old steak.
However, shooting animals from the air? That seems horrible and extremely unsportsmanlike.
At a standard beef slaughterhouse, approximately 250 cattle are killed every hour. They have their horns sliced off, they are branded, which obviously causes excruciating third-degree burns. On many occassions they are shipped without food or water to these slaughterhouses, and then a metal rod is shot through their brains and they are hung upside-down and have their throats slit. This is what is known as stunning. Because of time constraints, inadequate stunning is inevitable which usually means that a conscious animal is hanged upside down, kicking and struggling and bleeding to death.
