But he didn't want her to die. She, through her own agency demanded it & played the role of villain to take upon her the sins of her family. She refused to demonstrate the truth. As such, she, seemingly in tragic irony, dragged herself to the gallows to have herself executed. As strange as it may appear, she wanted to give the people comfort.
Was it unjustified? Was it a tragic, wrongful death? Yar! Nevertheless, she felt that her ignorance was her crime & thus she was guilty of the sins of her family, thus deserving death. As BS as it may sound (having a martyr complex), it was the sort of death that while preventable was more akin to suicide than execution. She was depressed, felt betrayed (because he didn't tell her the truth & let her live in sin), and felt that her relationship with him was all a lie. In truth, he
indeed loves her, but failed to recognize how he let her feel, how he failed to open up—his great mistake, and due to youth, his failure to demand the truth be known. He froze & didn't realize how she'd fail.
It was a great sin on his behalf, but not quite the same as simply having ordered her execution. It was more his failure for not better preventing it & putting a stop to it.
As a consequence of
both of their mutual "shortcomings", the Divine elements in the story deem fit to give them both a second chance (as is a common trope in these reincarnation stories).
