The whole “Lucius was abusive with Draco” thing has always been so funny to me. Really, I don’t get how people are able to believe something so silly.
Seriously, guys, wake the fuck up, if Lucius had been abusive with his son, he wouldn’t have been a part of the series. You know why? Because Narcissa “If you attack my son again I shall ensure that is the last thing you ever do” Malfoy would have killed him ten times in a row.
