But there were also some good robots in the Terminator.
"Watching John with the machine, it was suddenly so clear. The terminator wouldn't stop, it would never leave him. It would never hurt him or shout at him or get drunk and hit him or say it was too busy to spend time with him. And it would die to protect him. Of all the would-be fathers that came over the years, this thing, this machine, was the only thing that measured up. In an insane world, it was the sanest choice." - Sarah Connor, T2: Judgment Day
