The queen, she is such a failure as a mother:
1 - She spoiled her daughter(s) rotten.
Even if you think your children are the loveliest beings in the world, spoiling them too much is a big nope.
2 - After seeing the "future", she decided to avoid Pryde, thinking she will become a horrible monarch.
Seriously, instead of taking actions and trying to change the future, or just to mold her daughter into a proper human being, she gave up on the 1st child and thought of choosing the 2nd.
3 - She knew her daughter will be a huge bietch, yet she just simply ignore her, let her do whatever she please.
At least she should have someone keeping an eye on the future human disaster and report the actions regularly.
