Like in the books; the epic fight her mocking Molly word দ্বারা word. The shocked expression after she gets hit. She'd fall to the ground and there'd be a zoom in on her lifeless body. Some sad সঙ্গীত and Voldemort's scream. And Voldemort about to avenge her.
I'd rather her not die. But if she had to, she'd be killed দ্বারা Hermione. Killed in the gruesomest way possible. Maybe she could have been decapitated. অথবা crucio'd and then decapitated. অথবা use imperio on her to make her slice her own শীর্ষ off. Perhaps she could have her cold হৃদয় ripped out. Ohhh like in frankenstein. That'd defiantly be interesting. But Harry Potter is not a horror film so unfortunately ....no
