Beatrix had trust in Brahne. She herself did not know how Eidolons were extracted - she merely trusted that Brahne would not undertake anything that would put her own daughter in danger. Trusting that a mother will treat her daughter with care is a perfectly reasonable thing to do, especially considering Brahne had probably been very nice to Garnet throughout her life.You're forcing out extremely powerful creatures from a girl's body. This releases a large release of energy. And last I checked, large releases of energy were enough to kill people. There's no way she couldn't have figured out something like this, but she's still ignorant and dumb, either way.
Another point is this. If you're not a scientist, you don't argue with a scientist about matters of science. Beatrix knew little about Eidolons and she knew that Kuja and Brahne knew far more than her. Who was she to question their judgement on the issue when she had no expertise in that area?
You talk about it as if the fact it would cause harm was common sense. What you fail to realise is that there are a vast number of scenarios where the intuitive answer to a problem is the wrong one. Any intelligent person would know that you cannot make assumptions about what will happen in a given scenario - you need evidence to back up your point. Beatrix had no knowledge on the subject and so she stayed out of it, trusting that Brahne knew what she was doing.
Yeah, that's correct. She had faith in Brahne - and faith like that cannot be changed easily. Her conversion may have seemed overly slow, but in context it was realistic. Having served a Queen for many years, who you believe to be just, you don't suddenly turn your back on them after one dubious comment. Beatrix may have just believed it was a comment borne of anger and frustration with Garnet, rather than it being a genuine threat.No, she already made the choice to ignore her doubts, which is quite clear from "I'll kill all enemies of Alexandria!" right before she changed her choice at the last minute.
Just because someone says "I'll kill you", it doesn't mean they actually will. In anger, people say a lot of extreme stuff you know they don't really mean.
This is the argument Brahne would have presented to Beatrix:...so? Countries don't vaporize neutral countries because a few soldiers happened to flee to a neutral country. Not to mention that there weren't many Burmecians at all. They killed almost everyone in Burmecia, remember?
As far as Brahne was concerned, Cleyra was no longer a neutral country. It was harbouring the villain who had plotted against her - the King of Burmecia. And she could not allow the King to remain there, with the remaining Burmecians, in safety whilst he plotted his next uprising against her.
So instead she would crush all hints of a rebellion and utterly destroy any remnants of the Kingdom of Burmecia. The protection offered by Cleyra to these terrorists could only be considered as an act of war. The ally of my enemy can only be my enemy.
It's easy to see how Beatrix could have been convinced that attacking Cleyra was the only viable option.
But, since she was misled, she no doubt agreed with the cause - just not the means. If she had been perfect that would have been her moment to turn against Queen Brahne, but Beatrix's character is far from perfect and her loyalty allowed her to override any doubts over the extremity of force applied....which is like I said, Beatrix knew that it was wrong, but ignored it.
It's like the dropping of two nuclear bombs against Japan. As far as I'm concerned that was totally immoral - yet obviously the military did as it was told.
