Krishna describes the result of ignoring the divine. Their hopes come to nothing. Their actions bear no lasting fruit. Even their knowledge, however extensive, fails to liberate them. They remain caught in a deluding nature — what Krishna calls rakshasi and asuri prakriti.
These are not labels for any community or group. They describe states of mind. When a person turns away from the deeper truth and lives entirely in the grip of desire, ego, and delusion, that person's inner nature has taken on these qualities. The fix is not condemnation — it is the turn toward shraddha that Krishna described in 9.3.
