Andrew Hartford was selfish
 

Hartford is a horribly self-centered, self-serving person. If Spencer was around and Hartford was "on business trips" all season, it could've been much more enjoyable.

It was pretty irresponsible of him to build a son from scratch. Creating AI is kinda like playing God. But he did really love Mack. I think he lewrned his lesson, since he wasnt just gonna build a new robot to replace Mack when he died.
