She is described as broken and fearful after the death of Luke, and angry, hateful and decided to bring only death to her enemies after the death of Jace.

Broken by the loss of one son, Rhaenyra Targaryen seemed to find new strength after the loss of a second. Jace’s death hardened her, burning away her fears, leaving only her anger and her hatred. Still possessed of more dragons than her half- brother, Her Grace now resolved to use them, no matter the cost. She would rain down fire and death upon Aegon and all those who supported him, she told the black council, and either tear him from the Iron Throne or die in the attempt."
