Beyond Evil 

Men are sent into space to explore the universe. During their expedition, they encounter nothing but evil. It seems that theirs is the only planet in the now known universe where there is any good. So they build powerful robots and send them out to tame some of the surrounding worlds. The robots tame the worlds, but they also get caught up in the evil and return to their home planet several generations later. The men on the home planet dig up the old codes and use them to order their robots to leave the universe. The robots ascend to the fifth dimension and then return. But before they return to their home world, they create more robots with the same abilities as theirs, plus the ability to multiply and reproduce. Home World is overrun with the evil robots.
