Logic- She would realise her moral failure after the agressive talk she had with Hamlet but would be afraid to act on it.
I suppose if you let yourself learn from the failure then yes. As my dear Hamlet showed me, I committed a moral failure by marrying so quickly after the death of my husband. I'm not entirely sure how to go about fixing my wrong. ~Gertrude
Moral failure can make you a better person
Logic - She may nopt realise how frail she really is. For the information about the murderer of her new husband never reached her. She had no idea on Hamlet's true intentions with his confrontation.
I wouldn't say all women are frail but some are. I am not sure if I'm a section of the frail ones but i can see myself from others' point of view and consider myself frail. ~Gertrude
Frailty thy name is woman
Logic - Gertrude depends on others to make herself happy. At the start it was her husband King Hamlet and the love of their people, but when King Hamlet she clung to arms of the person who acted like he cared the most.
Some may think that but in reality it is impossible to not trust or depend on another person. Trust is the key to living contently. ~Gertrude
Don't trust anyone or anything
You cannot be content with anything if you let redemption stay in your heart, and revenge on high levels is a sin. ~Gertrude
In this time period, revenge of Hamlet's level is a sin so she would believe it best to move on.
Redemption is a romantic idea but what happened in the past is over - move on
