It is possible that Frankenstein would have died or lost his mind
Step-by-step explanation:
Frankenstein falls ill quite a few times in the book and effectively succumbs to his illness in the end too. in a way he is not as much of a hero because of the amount of whimpering that comes up every time his character faces adversity.
Right after the creation his 'monster' Frankenstein falls ill at the sight of his own creation and reels in the shock for quite a long time, all the while being looked after by his friend who helps him back to health again. His ailment came more from mental shock than anything else.
