The problem is that the story is filled with deliberate fallacies, "unreliable narrator" and all of that.

First, Aegon II was a power hungry prick and the dialogue that he would refuse the throne doesn't match his later actions well.

Second....why would Rhaenyra order the death of Helaena while letting Alicent live? Possibly she might want Alicent to suffer by having Helaena killed, but it was politically disastrous. Helaena had been friendly to Rhaenyra, granted they were on the wrong side but she had no direct reason to hate her with a fiery passion. There simply wasn't much benefit in having Helaena killed - we're only hearing half of what happened.
