Short answer: In some Jain traditions, Ravana is presented not as a deity but as a very learned and capable king who earned his powers through tapas (ascetic practice) and who was a devotee of Jain masters. This portrayal is used to teach that even great intellect and power can become dangerous when unchecked by inner discipline and right conduct. It also shows that Ravana is part of Jain Ramayana narratives to illustrate karma and the soul’s journey, not to serve as a model of dharma. There are differences between Digambar and Shwetambar tellings, but both view Ravana as a mortal, not a god, and not an object of worship. ( jainknowledge.com)
