That is a matter of opinion, she tells Harry all the reasons why she won't give him back the Swords.
And at that moment in Cold Days she was completely right. I would not have given them back either.
Then she violates one of the main rules governing them..
The rules are hard to keep for most people, even for most knights. Failing does not make you hypocritical, it makes you human.
It is not that she preaches another set of morals for others than those for herself. She already told Harry why she did not want to become a knight because she had difficulty keeping those rules. She is actually very honest about it.
And she did not preach the morality of the swords. She just recognizes what it is and what the swords expect. She never claimed those morals were here morals, she actually said they were too difficult for her.
It isn't about her picking up the Sword, that doesn't make her hypocritical.. After her very long soliloquy implying if the Swords got back in Harry's hands they could be misused but if they stayed in her hands they wouldn't..
She tried to do what was best. The Harry in Cold Days is different from the Harry at the end of Skin Game. That Harry got the swords back.
The Harry in Cold Days was a terrible Harry. Denying him the swords was the right choice and she explained it well.
It isn't about her using the Sword, it is about how she used it.
Failing does not make you hypocritical. Her emotions, her love for Harry, her anger just kicked in.
Hypocritical is about the morality you preach, and we have already seen she did not preach one, and the morality you live your life by.
She took the sword to save Harry.
Here is the definition of a hypocritical action;
When Nic surrendered, gave up both noose and coin, instead of accepting it as a Holy Knight, or knowing the rules for the Swords.. Judgement wasn't up to her, yet she felt that he should die, judged him, tried to kill him and broke the Sword.. That wasn't doing what she had to do, it was doing what she knew to be wrong after berating Harry
She did not berate Harry. She had the swords and she had to take a decision and she had to explain it. At that moment she did the correct thing. That does not mean she was the right knight material, that is why she did not take it up.
You forget Harry’s mental condition at that time and how Harry had warned everyone about what he would become.
about the rules governing the Swords and why they were better off in her hands. That my friend is hypocritical.
Explaining the rules of the swords has nothing to do with explaining your personal morality. I think the rules of the swords are on purpose too difficult to achieve for most people. Understanding them is something else.
That has nothing to do with it, if it made anything clear, it was she had no business keeping the Swords once Harry came back.
In Cold Days? That is not realistic.
She did not preach for others another morality than she believed for herself.
