Trubel would have to convince Nick she killed Trubel, get Nick out of the way so Chavez could recover the body, which would later come out of paralysis.

Nick knows how powerful Juliette is. He may be hoping that there's still some spark of humanity left in her. Juliette was rather convincing in slamming that possibility shut. Nick now knows Juliette has to die, because she's too dangerous to live.. Learning  Trubel did not kill Juliette will really piss Nick off.

Frederic probably ordered Juliette to go kill Nick.
