Most Indian traditions speak of “sin” as avidya, ignorance, literally “not knowing”.
I think it might also be worth viewing “sin” as a sort of tragedy, as a case where someone, not knowing their way, got lost in the darkness.
It would be the role of a shepherd to find such people, and bring them back to the light. There is nothing personal in any of this.
To be clear, I feel something best called evil exists, and must be fought, but how it is framed, precisely, makes a huge difference.
In dark moonless night, some of the flock wandered off. Now they have forgotten they are lost, or that they ever had a home.
Me, I’m lost too, but I know it, and that makes a large difference.
