Swami Mukundananda
Is avoiding my duty also adharma?
Running from duty is adharma
In Arjun's case, running away from the duty of his role would be adharma. Shree Krishna tells him the consequence will be narak, progress to the nether regions.
If you run away from it, it will be adharma, and the consequence will be narak, a descent to the lower realms.
