It happens in the wild, its going to happen in their enclosures.

I personally feed frozen/thawed or fresh killed, but thats only because I've had personal trouble with live rodents. Thats just me though. I'm not preaching to anybody to not feed live. If one of my future snakes refuses to eat frozen/thawed or fresh killed, so be it, I'll feed them live.

To me, its no big deal. I mean, the carnivorous people are eating dead animals right? The snake is simply killing its food and eating it, just like we do. The people on youtube don't want to see snake feedings, they don't have to search the stuff up.
