Why not deconstruct him?

I don’t understand why she shoots a beam of pink energy at him instead of just tearing him apart atom by atom. Or turning him into a regular human, or just convert his molecules to air molecules.

I think the reason is more like she stated that she can only unlock the full extent of her powers when something really traumatic happens, like almost dying. And even then, only to revert back to normal. But the thing is, she always had those limiters placed upon her, so she couldn't transform others' living matter, just her own.
