Hello Crimson Snow welcome to the forum.

The point that you make about Nicholas's devotion to his religion is, I think, very valid because, whether or not his decisions can be seen as justified in retrospect, he did not flinch from his faith even when faced with what must have been a devastation of all he believed in.
This leads on to another point which I have asked before.
What EXACTLY is meant by Nicholas' weakness?
There are many aspects of his character which show strength:
1. He had the sttrength of character to adhere to his faith in spite of his circumstances.
2. He had the strength of character to remain faithful to his wife - in spite of many opportunities to be unfaithful.
3. Physically he was a strong man, who exercised regularly.
4. He had the strength & stamina to work for long hours, often until very late at night, alone in his study.
5. He had the strength to stand up to his ministers when he decided to take charge of the army during WWI.
6. He had the strength to stand up to de Witte in the Russo-Japanese War.
7. He had the strength to stand up to Cousin Willy's threats at the outbreak of WWI.
8. He had the strength to accept his role as Tsar - even though it was not what he personally wanted.
9. He had the strength to maintain his belief in the divinely appointed role of the Tsar - again even though it would have been easier for him to abdicate sooner.
10. As a small boy he saw his grandfather dying after having been blown to pieces - & there is little reference to this in his later life.
11. He suffered terribly at the sight of his sick son, yet continued outwardly stoically as though nothing untoward was happening shows incredible self-control & strength of character.
These things may not (with the benefit of hindsight) always be to his credit nor were his beliefs always what we would regard today as reasonable. Nevertheless, HE believed them and had the strength to adhere to them.
Therefore I wonder again what EXACTLY is meant by weakness?
That he didn't do what people wanted him to do (is that weakness) ?
That he would not listen to the advice of other members of his family (is that weakness) ?
That he was concerned enough about his wife's psychological health & his son's physical health to allow her to keep Rasputin (is that weakness) ?
That he enjoyed being at home with his family (is that weakness) ?
That he wept at his father's death & found the prospect of taking on so difficult a role? (is that weakness) ?
Who can say what is meant by Nicholas' weakness?
