I'm already tried of hating only Cersei) On the other hand Qyburn isn't better. Actually he orginised explosion of Sept. He helped her in all hers evil acting. HE RESSURECTED GREGOR CLIGANE with help of necromancy. HE GAVE CERSIE extra power to act her evil acting and revenge to all (but two of her children died due to her fault, especilly Tommen!) Cersei is mad! But Qyburn isn't better.
Euron doesn't couse big anger anyway.....
