Although I find this episode to be excellent cinematically, it fails in terms of the storyline for the sake of drama. For this, you should view what Ford said about why the hosts are actually "free". The hosts are supposed to be "free" because they do not experience conscientiousness in the same sense that we do, I.e. "self-loathing, guilt" etc. are what us humans are supposed to experience and not the hosts. So at the end of the day, why did the (spoiler alert) host commit suicide (you know who) if he can't feel guilt and self-loathing as Ford had said in a previous episode.
