Iffin one is hunting legally, within the confines of the law, what their ethics are is really a moot point. Some states/regions outlaw hunting deer with dogs or any use of bait. Next state over it is legal. Now I have no desire to hunt deer or other game animal over placed bait, not do I have desire to hunt deer with dogs....but where it is done legally, I know others enjoy it. Kinda like ground swatting waterfowl and upland birds. Growing up as a kid, it was considered unsporting, and I still follow the ethics implanted in me by my mentors, many years ago. Wild Turkeys are considered upland game and it is considered unethical by most, to shoot them outta the air. Hunters are funny. My favorite type of deer hunting is still hunting in nasty weather. Have shot some of my best bucks that way and gotten a lot of satisfaction doing it. Still, when it came to bow hunting and now gun hunting for deer in my second half century of hunting, using a tree stand or blind is very effective....and gives very ethical shots. Killing a deer quickly and humanely is always what we should strive for......what difference is there if they don't know what hit them while lying in their bed, or while nibbling cow peas on a food plot?
Folks need to hunt within their ethics and the boundaries of the law. The first is subjective, the latter not at all. Big difference from the days when we had to kill wild game to survive than there is now when it is the sport and the challenge of the hunt that takes us afield, with the meat just an added bonus. The days where I had to come home with my bag limit in order to define the day as a success are gone for me. Now, just getting out and getting back is a good day. Nowadays, the sight of a Tom gobbling in front of me at 20 yards or a basket buck making a scrape at 30, doesn't necessarily mean I pull the trigger, like it used to. Sometimes, the desire to have more than one opportunity a year trumps having blood in the back of the truck that day.
So to the OP....do what you are comfortable with, confident in and proficient at. Do what is most favorable in the conditions and habitat you are hunting and is within the parameters of the law. Hunt the way that gives you the most satisfaction at the end of the day, regardless of what your friends or peers say......or random folks on internet gun forums. That is what is most ethical.
