Ben Lucas cherished Harrison Lucas dearly, and if possible, he didn't want Harrison to go through an abortion. He understood that with the child being older, the procedure would harm her body.
However, this child, his identity...
Ben Lucas didn't want to give birth to a child who would be inherently at risk. He knew very well the consequences of children from close-relative marriages.
Harrison is young and hasn't thought things through, but he had to guide her in the right direction.
He and Harrison love each other, and bearing no offspring is their affair, beyond reproach.
But if they leave behind descendants, it would be irresponsible towards their children and would invite criticism from others. He didn't mind, but he didn't wish for Debby to face blame.
