Bad, Evil
In Asia they assume everyone's heart is automatically bad and evil.
You don't want a bunch of evil in your heart, do you? No, I didn't think so.
あく, お
わる
None
Luckily, people in Asia know how to get the evil badness out of your heart with acupuncture (あく).
Acupuncture was originally invented in Asia a long, long time ago, to stop the bad chi from going through your heart.
