Do you think Harry could convince Hermione to join a cult?

I’m pretty sure I used the right flair. I hope I used the right flair.

Hear me out, Harry doesn’t know it’s a cult when he first joins. He is offered friendship, care, and a place to belong where his scar is just a scar and he isn’t the boy-who-lived just a boy-who-happens-to-exist during a time we’re he really needed it (summer following Cedric’s death). He is also introduced to a completely new magic system and “world”. No mention of the word cult at all.

But he finds the magic both fascinating and intoxicating. I figure he’d try and include Hermione not just because she loves to learn new things (and since studying is easier when she’s involved) but because it gives him an excuse to hang out with just her for extended periods of time.

However I’m also pretty sure Hermione would take little to no time to figure out something isn’t normal about the situation or the group.

Could Harry convince her to stay? Would her instinct to protect Harry cloud her judgement?
