I think he was refering to the really dark statement. IMO if you can see the animals vitals area then it is perfectly ethical to take the shot.
I also think that some computer ethics change drastically when they are presented with a questionable situation in the woods.I am not pointing fingers but it just seems to me that a lot on the computer scream ethics when they know good and well if they have no other choice in the woods that their ethics start to get a few grey areas.I don' t think it is done on purpose but self controll is the key.
This should get something started.
