Karate Kid Sequel

How does this show continue to redeem seemingly irredeemable characters?

I think by showing that they're damaged and that even if they're kind of over the top in their villainy you still feel some sympathy for them because of what caused them to end up there. There may be mustache twirling but it's rarely bad for the sake of bad. Nearly everyone on this show is carrying some hardcore baggage/emotional damage.
