I think Juliette had a different mindset with her power as opposed to Nick and Kelly. Nick and Kelly always knew they could be killed and we could look at the Mauvais Dentes as an example. Kelly explained to Nick how dangerous even just one of them was which is why she initially kept her presence concealed and then double-teamed him. Kelly was always extremely cautious until she wasn't in the end. That tells me she's very aware she could be killed due to any minor slip-up.
I don't think Juliette had any fear of dying once she gained control of her powers. She certainly wasn't strong-armed into joining the royals. She even warned the king against making a move against her even in a room full of place full of people there to serve him.
