Yes. In Jainism, the soul (jiva) remains bound by karma through many lives, but liberation (moksha) is possible for every jiva once all karmas are purified and destroyed. Rebirth in a lower form or in Naraka (hell) does not permanently bar moksha; it only postpones it. Ultimately, by proper effort—samvar (stoppage of new karma) and nirjara (shedding of accumulated karma)—a soul can burn away all karmas and rise to Siddhashila as a liberated soul. Human birth is considered the most favorable for making steady spiritual progress, but even from lower births one can continue the path toward moksha. This is a core Jain principle about the persistence of the soul and the possibility of ultimate liberation. You can read more about afterlife, rebirth, and liberation here and about what happens to beings born in different realms here .

Note: In Jain tradition, there are two main paths to moksha—through right faith, right knowledge, and right conduct (the Ratnatraya) and through steady shedding of karma. Both Digambara and Śvetāmbara agree on the essential aim of complete karma destruction, though some details of practice and cosmology may differ between the lineages.
