well its the exact same concept as humans observing animals on earth. When our purpose is benevolent in nature, we simply observe from afar and
don't disturb them at all.
BUT, when we have other interests that requires a closer look, we tranquilize and 'abduct' them.
I don't see how this is any different than aliens. They simply have different methods of observing and abducting. In the end, we are still safe
though.
