Finding it to be the best opportunity, Richard pierced the sword right through Charles's heart. He twisted and turned it, pushing it further into the man he despised more than anything in this world. He wondered if the sword wasn't working because Charles was just standing there unphased.
Abigail was also confused why Charles did not instantly disappear and stepped forward to help Richard but stopped when one of his fingers started to disappear. Maybe it took longer depending on how strong the person was.
"No," Charles pushed forward to get the sword out of him. He was not ready to die. "I'm going to kill all of you. Get this thing out of me!" He yelled, feeling more of his body slowly fading away.
