When you hurt someone, it initiates a chemical reaction in that person’s body that changes his/her mental condition. That means you are disturbing the arrangement of subatomic particles like protons and neutrons. These particles are the part of the grid that holds all the particles of the Universe. To reset this disturbance of grid caused by you and according to laws of nature, the Universe will go to the source and destroy it. So, it’s better to say a simple word “sorry” and reset the arrangement yourself before the Universe.
