Death was painful for only a moment, but having a baby was torture that lasts for years, if not decades. Taking care of a child while losing all the sleep was not something he wanted to experience.
He believed life turns into hell after having a child since the parent has to make the child the center of his world. A parent can no longer give priority to his own dreams as the entire focus was reserved for 'the bundle of joy.' He could never understand why parents would sacrifice and suffer so much for the sake of their child.
Perhaps living the life of an orphan—despite having parents—made it difficult for him to understand how a parent-child relationship worked. While he hated his own parents for what they did, he has never let his hate turn into a bias.
Otherwise, he would not have been touched by the actions of that woman in the slum. She distributed the food among her children while she slept on an empty stomach.
