Which hitman goes to the target's house and kills everyone in it except the target?
That's what I mean
So it's either 1) the husband was the target 2) the judge is still needed for something, so that's probably a case she is working on and can't be passed to another judge (nothing related to the hitman probably)
Another point would be that, since they killed all her family, what can she lose now? I would take the risk of being killed but fuck properly those who killed my family
