Jamie/Clint
In his case, ignorance just leads to cruelty.
It's not like that at all. I'm related to these people, Clint. They're all my cousins/ancestors. If you step a toe out of line, you get disowned. Married into the wrong family or married a muggle? Disowned. Don't go into the profession your parents want? Disowned. They think there is no such thing as dark magic. They think Muggles are scum. The ones closer to my generation literally joined up with the evilest wizard to ever exist in an attempt to enslave Muggles and Muggleborns. The only good one left was my father's godfather.
