If Baek Young (and whoever is the God behind her) hated Seo Gangrim so much, why didn't she kill him when he was a kid? Instead she killed his parents, let him live depressed and alone for years, and when he finally made friends and comrades, she slaughtered all of them too before she finally killed him.
Was there a reason to make him suffer so much before killing him? It's like they wanted to break his spirit and make him as desperate as possible before taking him.
