Even when people are intentionally being malicious?

Sorry, but I will never, ever accept live feeding a ferret. Or intentionally throwing a rat to a snapping turtle and posting it on YT for the lulz. Those sorts of things. It just simply isn't needed at all, it's unnecessarily cruel. Seems like it is done because the owner gets a kick out of watching things die. I have no issue with those who live feed if it's a last resort... but I'm hearing stuff like "because it's convenient". Well, I'd like to see a decent backup of that argument because is that little bit of convenience worth the risk to the snake? I don't understand how it's any more convenient feeding live when with pre-killed, there is no issue of the animal biting back, no issue of prolonged suffering to the prey animal and no issue of parasites. Cheaper in bulk too (depending on where you live).

Now if this convenience comes from the fact that the snake cannot be fed f/t for whatever reason, then fair enough. I can understand. What I can't understand is doing it even if the snake accepts f/t.
