Remember guys, we are talking about this guy's business and the way he makes a living to feed and support his family. Obviously you don't have all the facts, because I seriously doubt he would be given a permit to kill all the deer affecting his crops unless it was a major problem. That being said, if he is senselessly killing all the deer just to be an a$$hole, then I'm right with you. However, if the deer are really hurting his business I see no problem with what he is doing.
