Bhagavad Gita · Chapter 16: The Divine and the Demonic Natures

Bhagavad Gita 16.6

dvau bhūtasargau loke'smin daiva āsura eva ca | daivo vistaraśaḥ prokta āsuraṃ pārtha me śṛṇu ||

There are two kinds of beings created in this world, the divine and the demonic. The divine has been described at length; now hear from me, Arjuna, about the demonic.

Modern context

Two kinds of beings: divine and demonic. Now Krishna turns to describe the demonic at length. Why spend so long on the negative? Because it is useful to recognise it, in others and in oneself. Most people have some of each. Knowing the signs of the demonic helps one notice when it is starting to take hold.
