Large boidae can and will kill humans. Children or women can fall to prey to green anacondas or netpythons. Those animals are dangerous
They are not dangerous if a bit of common sense is used. If you do not know how to handle a snake, when you see it, keep a distance, it is not going to come after you and I am sure you could run much more quickly than a large python if it did (which it wouldn't). Keep in mind, more people dies from random pieces of airplanes falling out of the sky than from snakes.
