Daddy Issues: The ShowElsie is the key!
Ford wanted Elsie dead, Bernard has developed super daddy feels towards her, and while he couldn't "not" kill her, he by passed the kill order and put her away w/ a bucket and food.
Ford has Maeve, whom goes for her daughter
Human Bernard has Dolores, whom goes for her father
Robo Bernard has Elsie,
this is the aberration that Ford did not plan for.
