While that hardly makes her less unlikable, I think people need to come to terms with the fact that she doesn't intentionally "murder the child" as many keep claiming.
The scene is intended as her threatening the girl with a punishment, with the snake being there just as a tool of intimidation... Except things go out of control.
You can also see in her face that she immediately regrets everything when the kid dies. Even with the kind of rough animations the game has right now it looks like she's fighting back tears before she regains control of herself and goes back to putting on a brave face to seem like she's still in charge.
