Carla can't "obliterate" anyone. The best she could do is go around punching and kicking them and hoping it was hard enough to knock them out.

Let's face it, except for the added mobility of her Aera magic, her battle prowess is that of a moderately trained, but completely normal non-magical Human. There's not even a garantee (or a good chance) for her to win against a well trained non-mage. Just look at the Vanish Brothers. One of them should easily be able to finish Carla off in a one-on-one.

But more importantly: Carla had just enough time to rush to Wendy and push her out of the way of the attack. If she'd been one or two steps further away, Wendy would have been hit and would now be dying or maybe even outright dead.
