Max Villareal - Evil or Not Evil?

Personally I think Jacques isn't insane, but rather just weird. He's described as having eccentric habits which makes sense considering he wants to walk around a hedge in knight armor. Plus it's implied that the "death" of his wife hardly changed his kids, the teens are relatively normal and Max is still a "terrifying force of nature". So for all we know she could be a criminal just laying low and occasionally visiting.
Over all nice theory, it got me thinking.

also just saying an evil person being nice doesn't exactly mean they aren't bad, same with a good person being rude. Some villains can generally be great people that won't hesitate to hold the door open for someone or help an elderly person cross the street.
