Debt of gratitude is not a demandable right
If the sole intention of a person in showing goodness towards others is to get anything in return, such would be a grave misconduct.

Debt of gratitude is not a demandable right.
If it were, it would not be called as such and any lack thereof would not be viewed as an imputable sin.
Any form of perverted view on this virtue must rather be represented by another word or phrase.
Perhaps the “enforceable contract” would suffice, where the meeting of the minds is made by parties, laying explicit terms in a document, and having it effective as deemed by signatories.
However, due to the inestimable value of acts of kindness thereby hampering the creation of contracts, debt of gratitude would remain as an inherent Filipino values, where only the conscientious and kindhearted would likely to express in the same degree or beyond.
Further, if the sole intention of a person in showing goodness towards others is to get anything in return, such would be a grave misconduct.
To the pure-hearted, however, though disappointing to remark, only God can reward, in ways incomprehensible.
Or any universal force that maintains equilibrium.
