I was given this riddle about character I made. He is an orphan, which the first half of the riddle signifies, but I can't get the rest of it

"Sorrow, the parents that outlive their child. Sorrow more, the child who outlives their parents. Sorrow breeds sorrow, forevermore the man who must slay his father. He will beg for you to whisper, but all will be lost in screams."
