Oh yeah! Oku is never shown 'erasing' another living being, though it's presumed he can do so. His range is limited (ranked a D), and an example of him erasing things is kind of like this, where he was swiping at the ground to attack something.
The swing of The Hand's right hand is probably limited to about that kind of range. Is that okay?
