In essence, even if you try to explain Rhea by giving her human flaws, "she's just traumatised", you inevitably arrive at the following complication. Rhea can have human flaws, yes, but they are amplified by her living for inhumanly long into something larger than what the hate of a single person could ever be. To make matters worse, that weak, traumatised and fallible person is given the power to rule an entire world.

This is the core of why FE makes dragons out to be the enemies. This was the case with Medeus and the Earth dragons, it's still the same with Rhea and the Nabateans. The good manaketes like Tiki and Flayn have always been the ones that choose to sleep for those years rather than stay awake. Seteth and Flayn have forgone their monstrous forms to live as humans among them. This is how good Nabateans are. Much in the same way as Edelgard's error in Azure Moon is shunning her humanity completely. It reveals the root cause of the antagonist's error. It even has intentionally green blood to prove what Edelgard has been warning people since the beginning: that they are inhuman monsters with no care for human life; a common thematic in fiction to show how alien some fantasy monsters are.

Now do you see the destruction divine dragons have wrought?
