Answer:
Excessive ambition for her husband
Step-by-step explanation:
Lady Macbeth is an ambitious woman who can never settle for less. She wants her husband to be at the helm of affairs. She doesn't want him to serve but wanted him to be served. She's not content with patience.
After Macbeth's encounter with the witches and the prophesy, she became overly ambitious. When Macbeth was reluctant about the murder she took it upon herself to get the deed done.
She's more obsessed with position rather than money, was not prone to fear about her husband's safety in battle and was not insecure about his love for her.
