Is shame and remorse unskillful? I read this in another answer on this site:


  "and later I regretted" -- remorse is a klesha, an obscuring emotion.


my person thought it's worthy to lift the question if shame and remorse (before, while and after a deed be mind, speech or body) are generally unskillful, therefore to be abandoned, or if certain shame and remorse is actually skillful and very needed, therefore to develop and relay on it.

(Note that remorse/kukkucca, as a hindrance, falls by abounding sense-desire, end of reason for ill-will)

Feel invited to reflect, and possible share even Buddhas view on this mind qualities: An invitation of shameless making merits, so that one might not feel remorse, having not done, later.

The other answer on this site was fine in its essence, spirit, purpose &amp; intent. 

There is the unwholesome 'remorse' or 'guilt' (kukkucca), which is a hindrance; and there is the wholesome 'sense of shame' (hiri), which is a virtue and one of the five gates to Dhamma. 

As the other answer on this site implied shame towards unskilful deeds is for a Buddha a means of learning a lesson and moving beyond guilt &amp; remorse. 

The Lord Buddha said: 


  He who having been heedless is heedless no more, illuminates this world like the moon freed from clouds.
  
  He, who by good deeds covers the evil he has done, illuminates this world like the moon freed from clouds.
  
  For it is a cause of growth in the Dhamma &amp; Discipline of the noble
  ones when, seeing a transgression as such, one makes amends in
  accordance with the Dhamma and exercises restraint in the future.
