Yes, he was filled with immense regret!
His mad revenge, his wanton behavior, had destroyed the life of an innocent girl, causing her to endure immense pain for seven years; to be humiliated, cruelly abandoned, forced to endure the torment of childbirth, to struggle for survival in the cracks of life, and upbring two children amidst hardship...
The harm he had inflicted upon her was bloody and ruthless.
As for the two lovely children, he had never once cared for or nurtured them, had never taken on even a sliver of responsibility as a father; instead, he had used them time and again, to coerce her, to threaten her.
He had done many, many wrong things, yet she bore it all in silence, never giving up on the strong, violent child, but rather, giving birth to his child and raising them to be so large, lovely, and smart.
