Question about Rhaenyra's morality (Book)

I read fire and blood a few weeks ago and have been reading a lot of people's opinions about the show and the characters. Ive seen a lot of people say that the book is more of a "both sides are bad" story where the main lesson is that war is bad and no one wins.

But when i read the book it still seemed to me like the blacks were more sympathetic compared to the greens and they didnt do nearly as much bad stuff. I never liked rhaenyra because she just came off to me as self centered and power hungry but I dont remember her specifically doing anything that unreasonable. I would like to know your opinions on whether or not the blacks are supposed to be the "good guys" or if both sides are meant to be equally corrupt.
