I think it must be a single word from something like "willful insistence on wrongdoing." What is that word? A lot of websites say "happiness" which seems obviously incorrect.
Perhaps profligacy? Oxford defines profligate as
Licentious; dissolute: he succumbed to drink and a profligate lifestyle
As similarly, the referenced licentiousness and dissolution.
The simple antonym is unrepentant
Showing no regret for one’s wrongdoings: he was unrepentant and said that his comments were completely accurate
