Jorma: While these machines are merely products of their programming, Sever is working towards making robots with souls.
Panthro: Machines with souls? That's impossible!

The Soul Sever being obsessed with bringing his deceased family back to life is something of an in-joke towards his voice actor, Jeffrey Combs; Combs' most memorable role was as Dr. Herbert West in the Re-Animator films. In the films, Dr. West was obsessed with bringing the dead back to life, much like the Soul Sever.
