"All men command women, we command all men, and our women command us." - Cato

This is a very successful woman, career wise. She’s clearly not incapable of navigating high stakes power dynamics and you shouldn’t just absolve her of responsibility in this.

(Your second statement carries far more weight)

We don't really have the ability to judge the power dynamic without intimate knowledge of the people and their personal lives, we don't even know when things started and what place their lives were in then.

It's why we generally frown upon relationships if there's any direct business link.
