While I don't personally use snakes as feeders, I doesn't bother me seeing BPs or other snakes used as feeders. BPs, including morphs, are some of the most common feeder snakes in the reptile world.
Just like our snakes have to eat rats, some snakes have to eat other snakes. I've seen a few cobra, monitor, and frog keepers feed balls to their snake eating animals. And animals like King Cobras cannot eat any other prey(I.E. with fur) because they evolved to ingest specifically snakes. They do not thrive on any other diet. And other furred prey like rats have been seen to actually give them internal and digestive problems.
I'd rather see a snake become a feeder than it go to a bad home and suffer slowly or thrown away/released into the wild(we all know its happened).
