Feeding live to an animal that eats frozen is foolish. Leaving aside the difference in how humane the death of the food animal is, there's a real risk to the snake. I had a Bronzeback Snake, which is mildly venomous by the way, killed by a mouse when I got impatient and fed it two mice at once rather than letting it finish one before introducing the second. If you want to get your jollies watching animals die that's fine, but do it right. Get yourself a Cobra and a stopwatch.
