A lot of people like to watch it...I feed live, but rarely ever see my snakes strike, as I'm interested in them eating, not watching them "hunt".
To me, a snake killing and eating a rodent in a small enclosure is "hunting" on the same level as putting a deer in a dog cage and shooting it. Once that rodent is in the enclosure, the "hunt" is off...it's already dead, just living on borrowed time.
