I was thinking that hurting others is a form of passing on ones own shame. (If I shame you I don't feel my own shame.)

Of course this is a simplification, human relations are hugely complex and there are are many reasons why humans hurt each other.

This one just came to mind as I was thinking if someone ever tries to put you down (hurt you), one response is to say I don't think I'm going to be shamed by you today.

Take care.
