After the damage that was done to my first bp shortly after I got him by a live mouse I swore I would never feed live again. They may do it in the wild, but that's why most wild snakes have shorter life spans and don't exactly look the greatest with all the scars on their bodies. And I guess some people, just because they don't hear a scream or yelp or squeal from the snakes as their being bitten, don't realize just how bad it must feel for them. Especially if you've ever seen how deep those rats sink those long front teeth into them an just start gnawing away.
I just can't in good conscience sit there and watch a rat gnaw on my snake while it's trying to constrict it, not any more. Even using live for a month while transitioning my non-feeder male boa pained me, that's why I'm glad I made sure to try every single possible option so I wouldn't have to give in and go with live feeders.
