The Differences Between Premeditated and Passionate Blitz Attacks

A blitz attack could be either premeditated or a crime of passion. If she did get the poison, then clearly this was premeditated. But we also don't know, is it just that she made up her mind and then she grabbed the axe? Because it's what I do think she used the axe because it was what was readily available. There's so many factors. Unfortunately, so much of this happened behind closed doors that we just don't know everything that was going on in that household.
