I'm really confused now I really don't know who's good and bad in characters

Yehwa is not bad, she was just chosen as the 9 sin whatever they call that. The blood chose her not her choosing to become a demon. She doesn't even like to use that power because she's afraid she will hurt everyone she loves. She's helpless, she's a naive and weak little girl. Bullied since she was born. She can't even talk.
luckily i found the raw novel for this
