ethical is a word that people will always debate do to the difference in hunting and life styles,If I can go to sleep at night without questioning my actions during the day then it is "ethical" to me,and thats all that matters!I hunt for me,I decide if the arrow leaves the string!Do cameras make it easier,I have used them on and off for years and I would say,in my case no,you still sit you still have to pull off the shot you still have to blood trail you still have to drag the animal,woodsmanship should not be in question you have to figure out where to place the camera,if you think you just put them in the woods and deer just start showing up your wrong.Benefits of the camera over the years is I have caught 2 trespessers on my lands and have been able to show them and now the stay off with involving the police,upstate NY had close to 25" of rain and very high winds,I hunt a oak ridge and knew the acorns could be gone off the trees and in fact some of the trees are gone,so I sat my stand one night with my son and saw 1 doe after 3 hours,then after 6 hours of scouting moved some old stands 7 to be exact,in 6 hours I heard 3 acorns fall from the trees on the ridge,not a good sign,past years your would need a hard hat in there.So I put a camera in for a week and saw plenty of deer still there and turkey,and ticks!!So I pulled the camera because of theft issues in the past,and I also dont like going in to check pics every few days do to jumping deer and leaving scent,so now I know the deer are there and I can use my limited time to hunt hopfully a productive area.Using the cameras is also fun because you can share pics with your family and friends so they can see whats in the woods and could maybe spur a new hunter?Ethical is a word that will always bring in emotion,I will always make it up to me,I have to live with my action not you and like wise,so I wish everyone good luck with or without cameras,carbon,allumium,wood arrows,what ever broadhead,scent killer spray or machines or nothing,factory bows,custom bows,ground hunters or treestand hunters,etc,etc,etc,just remember we are all on the same team to keep the outdoor lifestyle alive and well,so last but most important before any of your equipment goes in the woods be sure your kids are with you first so they can carry the lifestyle on,they way they choose to!Good luck shoot straight!
