Bhagavad Gita, Chapter 16, Verse 7

The persons of Asurika nature know not what to do and what to refrain from; neither is purity found in them nor good conduct, nor truth.

A real, basic confusion is named here first, not even knowing right action from wrong.

Krishna doesn't start with dramatic wrongdoing, he starts with something more fundamental, a real failure to tell proper from improper at all. Everything else follows from that root confusion.
