Okay so I remember this scene from a movie where this dude has captured this other guy, they're in a forest or a field, somewhere outdoors. The captured guy is being held by two goons, and the main boss dude approaches him, and pulls a snake out of a sheath on his belt. I think they were interrogating the guy or something, anyway main boss dude puts the snake up to the captured guys face and makes it bite him. That is all I can remember, but I think he kills more people this way. Only other thing I can remember is seeing this a really long time ago, when I was a little kid. So late 90s early 2000s.
