Can Law even hurt anyone?

[Warmmedown]

It doesn't hurt them when he separates them.

Can he kill Aokiji by removing a proton from all his brain cells? I guess it still won't harm him. Can he just kill Shanks with radiation? Send loads of protons and electrons at him.

His awakened devil fruit powers seem pretty crazy. He can basically activate Gamma Knife from within anyone's body now but an advanced version of it.
