By this theory of prayaschitta , the Shastras by following a spirit of compromise have given caste a perpetual lease of life and have smothered reflective thought which would have otherwise led to the destruction of the notion of Caste.
This tactic is deployed in Islam too, that Allah is merciful and if someone prays from the bottom of their heart - He may forgive him/her for all the sins. If you ask a hypocrite believer, he will say “humans are never perfect and we can always ask for forgiveness”. Lease for life.
