So far, this story feels like it was written by an engineer. I'm more or less sure that there are going to be top-tier political conflicts with the neighboring countries, a few assassinations and failed attempts, and precognition actually relevant to the plot. In the meantime, all the characters seem to have exaggerated caricatures of actual personalities. The problem is that there's too much care and planning into how the character personalities develop, which implies the exaggerated personalities were a choice by the author. If so, I have no idea what made the author choose such a decision and can only hope the future chapters will be worth it.
Anyways, it seems the original Pryde personality was forged from neglect, and then she tries to draw attention to herself as a reaction to that neglect. More likely than not, everybody who knew the Queen's predictions were aware of her doomed future, and as a result the one and only human emotions Pryde had been exposed to was fear (of her future actions and destroying the kingdom somehow), disgust (of who she is, and how she acts towards all the people who hate her anyways), hate (I mean, it's very easy to interpret her parents' actions as hatred. They literally supported a ditzy younger sibling for the throne for seemingly no reason, if Pryde wasn't aware of the rationale to the Queen's actions), and general neglect (think of Naruto, Gaara, and Sasuke growing from childhood neglect. I know IRL examples, but I can't explain using people I know as analogies, so instead I'll summarize it using the anime format: childhood neglect = drastic actions taken by actions = pure evil or pure good, no inbetween.)
Anyways... MY FREAKING GOD THERE IS AN ACTUAL EXPLANATION TO WHY THE VILLAINESS HAS A SADISTIC PERSONALITY FOR ONCE! aslkjfdlkasjfien
