I don’t think anyone would let their 14-year-old child run off to be killed in an already established unjust war to be sacrificed.
But we don’t know that it was an unjust war. And the situation may have been the dire. They may have really needed the soldiers. It may have been a stay and die or come and fight situation. Though honestly i don’t understand why they didn’t take the parents and not the children. It is just not that simple. And Rumpel had a choice. That is all i am saying.
And Bae was being brave, saying he would go, Rumpel murdering someone to gain power which he then used to harm people for centuries was not brave or good, in my opinion. And really there is never no choice. There is always a choice.
