Is it still wrong to spit on a person's grave if they were an awful person?

My paternal aunt (dad's older sister) died several years ago. I visited her grave and spat on it. I said out loud that it's great that she's dead and how much I've been waiting for that moment.

She treated my mother like garbage, never owned up to her wrongs, nearly sabotaged my parents' marriage by telling lies about dad having an affair (it was confirmed a total lie), stole money from others, etc. She was a lost cause, an awful person.
