Don't do it, brother. Lions usually go straight for the kill, but you can't count on that. Being eaten alive is one of the worst deaths imaginable.
I've seen videos of people being attacked like that, it's horrifying. There's also this recording of a guy who was obsessed with bears. He truly believed he had a special connection with them and spent most of his summers in national parks trying to get close to them. He refused to carry a gun or even bear spray because he was convinced the bears trusted him.
In the end, he and his girlfriend were both killed and eaten alive. There's an audio recording of the whole thing and it's absolutely traumatizing to hear. I'm going to link it just to show you how terrible that kind of death really is, to make you think twice about this method.
