If we just kill Kattrin then she won*t be in danger.Cindy has already been captured. It is going to be hard and dangerous and maybe counterproductive to try to reduce her.
Lydia may also already have been kidnapped, or may be just about to be kidnapped, and every minute we spend doing something else rather than warning her is increasing the likelihood that she is and that her bodyguards are killed in the process. This would possibly seriously endanger her father and so may make the world itself very significantly less safe by risking transferring his power to an enemy of existence.
All we need to do is make one phone call and we can warn her and through her or the bodyguards warn her father to take precautions. That would be trivial for us to do.
We have so far chosen not to do her and deliberately leave her and them in ignorance of the very quite possibly imminent lethal threat to them. We are doing nothing at the moment to prevent her kidnapping, which I say again, could happen any moment. Katrina very likely has allies who are taking care of that, so even killing her right now may not save Lydia (or anyone with her; like Daniel). Indeed; if Lydia and anyone else have already been captured or are captured in the time it takes us to go to and fight Katrina then killing the latter may trigger the murder of the former shortly afterwards as said accomplices cover their tracks.
And the Crown is line of sight. We've missed the chance to use it on her.
Saving Matthew's grandchild either gives us a clear shot at Kattrin as the very next action, or it even forces the confrontation if she is near the site where the girl is held.
The Ankou, if he is actually Lydia's father, is the most distant target involved in all of this and definitly won't die without a proper ritual first, so he is safe to save for the last.
Best case he never even knows that someone was after him and instead finishes his job of perma-killing the Capricorpus without our input.
