Be real careful with your comments starting off here, person123, you're new here and start off with a some what loaded question so you probably ought to figure on getting some guff just to check you out to see what you are about. Trolls are not welcome on anywhere; not saying you are one, just giving you an honest heads up. Now to answer your question. I kill coyotes for many reasons; depredation of livestock and wildlife, disease and population control, and because they are pretty wary and intelligent critter that is fun to match wits against. If you care to do some research on your own you can find several documented cases of coyote damage/depredation dating back several decades right up to the present. In the midwest they have become so thick in some areas that the mange has reached epidemic proportions and the coyotes have really dropped in numbers due to disease. I am going to assume you being from New York that you have never seen a mangy coyote up close. Generally they have very little or no hair and are covered in sores from constant rubbing. Most of the time the sores have become infected and stink to high heaven. Now, imagine a hairless, infected, weak coyote trying to survive even a mild Midwestern winter, let alone a bad one. They generally wind up dying of starvation or exposure; not a good way to go. However, like I said before, the information is out there, documented, so if you would like to do your own research on it you can, and won't have to listen to all of our opinions.
p.s. your intelligence sensor is way off base and needs re-calibrated.
