i hear what you are saying, but remember that your are not trying to kill off all the coyote, you are trying to keep them at them at appropreat levels of population. coyote do have a perpouse. coyote are one of natures ways of ending the suffering of week or sickly animals. there for if you fatten up the remaining population you are helping them stay healthy so they can do there job. you can not make a coyote too healthy. you can only let the pack get to big. so i say kill as meny as you want, and if it is ok with the land owner to leave it and you dont want the pelt than there is nothing wrong with leaving it. as for teaching your son. i am in the same position that you are. my son is 7 and i would be madder than all get out if he wanted to kill a deer and just leave it. but would not feel bad explaining the difference to him, because in a way by haling the coyote out of the woods and burrying it you are alowing its meet to go to waist there for in my view it is more ethical to leave it out for the other coyotee to eat. again providing the land owner dose not have a problem with you doing so. sorry if that made no sence but it is how i feel.
