Menarik, nih. Nothing is less evil. If I have to choose, Santet. Nargetnya bisa ke orang lain dan tanpa sepengetahuan orang itu. Like once said, human are scrarier because they have mind and feelings. Once their feelings hurt, the mind got darkened it became full of hatred. Efek pesugihan juga jahat sih bisa sampe 7 turunan but I'd go with santet
