Honestly I hoped they’d feel disgusted about it because Hermione had treated them like the rest of the Wizarding world treated muggles. Their opinion didn’t matter, she didn’t even ask them, she just did it because she could. I love Hermione but there was no logical reason for what she did nor do I see her as a victim (as some people do) for it. They would have moved to Australia and stayed out of harms way if she’d just explained what was going on (and nothing terrible - beside their own daughter stealing every memory they had of her - did happen to them).

Again, people don’t have to agree but I would not be able to just go back to a normal relationship with someone who did what she did.
