"You knew what i was when you picked me"

In the video the boy went hiking up a mountain and when he got up the mountain there was a rattle snake and he told the boy to take him down the mountain because he was cold and hungry and that if he helped him the boy would be special but the boy told him no because he knew what rattle snakes do so the snake persuaded him to take him.so the boy took him down and when he got to the bottom he put him down and the snake bit him and the snake told him "you knew what i was when you picked me up". I think the boy did the right thing for rescuing the snake from dieing but the snake did the wrong thing because the boy helped him when the snake couldve died.
