Why?Sin and virtue both dependent on each other.
Why?Existentialy nothing is Sin or Virtue but it is our believe, conditioned mind, and social norms which defines.
Why?For persons like Jesus, they has no firm distinction in Sin and Virtue. Their act / behavior is beyond both.
Why?One thing is very clear that person like Jesus has no possibility to go against Dhamma/ Dharma
God bless,
