What is the implied difference between shall and will here, in Frankenstein, if any?
In one part of the book:
"Beware, for I am fearless and therefore powerful. I will watch with the wiliness of a snake, that I may sting with its venom. Man, you shall repent of the injuries you inflict.
Devil, cease; and do not poison the air with these sounds of malice. I have declared my resolution to you, and I am no coward to bend beneath words. Leave me; I am inexorable.
<<It is well. I go; but remember, I shall be with you on your wedding-night. >>
I started forward and exclaimed, Villain! Before you sign my death-warrant, be sure that you are yourself safe."
Then, a few sentence later:
"I would have seized him, but he eluded me and quitted the house with precipitation. In a few moments I saw him in his boat, which shot across the waters with an arrowy swiftness and was soon lost amidst the waves.
All was again silent, but his words rang in my ears. I burned with rage to pursue the murderer of my peace and precipitate him into the ocean. I walked up and down my room hastily and perturbed, while my imagination conjured up a thousand images to torment and sting me. Why had I not followed him and closed with him in mortal strife? But I had suffered him to depart, and he had directed his course towards the mainland. I shuddered to think who might be the next victim sacrificed to his insatiate revenge. And then I thought again of his words --
<<I will be with you on your wedding-night. >>
That, then, was the period fixed for the fulfilment of my destiny. In that hour I should die and at once satisfy and extinguish his malice. The prospect did not move me to fear; yet when I thought of my beloved Elizabeth, of her tears and endless sorrow, when she should find her lover so barbarously snatched from her, tears, the first I had shed for many months, streamed from my eyes, and I resolved not to fall before my enemy without a bitter struggle."
