Pythons are very effective killers. While they are non-native to the United States, they do have a habitat where they belong.
We can not be sure where this video was recorded. If it is in an area non-native to pythons, such as Florida, they need to be killed. If this is the Snakes’ natural habitat, the snake needs to eat and be left alone.
Most comments praised the individual for saving the fawn. My perspective depends on this being the snakes’ natural habitat. Snakes are animals as well and should be protected in there natural habitat.
