Expressing a feeling of sorrow or regret over one’s wrongdoing, though could go a long way, but mightn’t be enough to appease the offended party or smoothen the resulting frictions.
Feeling sorry becomes comedic and makes no iota of sense if it doesn’t make you refrain or halt you from a wrong course.
Except it’s Herod’s kind of remorse:”And the king was sorry, nevertheless…beheaded John…” Matthew 14:9-10.
He claimed to be sorry, yet went ahead thereafter and killed John the Baptist! He was sorry indeed!
If that’s how sorry you are for your wrongs; there’s no difference!
“…ye were made sorry after a godly manner…For godly sorrow worketh repentance…” 2 Corinthians 7:9-10.
