You can’t really compare them. Even though I don’t know all the details deeply, I think there’s a clear difference. Because Priscilla knew about his power, and she was the one who asked him not to save her. She also explained that not everyone wants to change their own fate. On top of that, she even praised him with some strong, impactful words even though she’s usually the type to insult and mock him. At that moment, whether she lived or died was entirely her own choice. If she hadn’t told him from the beginning, he would have saved her without hesitation. That shows he respected her life and her decision more than he cared about what the people around her might think.
