Jeez i feel like im repeating myself... You know what programing is ? When a program as 2 option and make a choice because of his programming? Web site that can actualy guess what your thinking about by answering question and they get better each time as they adapt. Those fucken jap toy that use to be a little thing where you have to take care or whatever of the little baby that been programed into some sort of watch. Those little dog they make that actualy simulate a need of affection and simulate the action of showing it. Do i really need to name everything that already exist to explain the coding of a techonology from years 2300 in chrono trigger ?

Marle is afraid of Lucca trying to fix robot as she say "It might attack us"
Lucca clearly say "I will make sure he cant"
"Robot are not evil. human make them that way"
Having a will make it possible for anyone to be good or bad.
Robo was programmed by Lucca to be good. It has no will of it's own.
remember also when Spekkio says that he is a huge toy ?
That Robo cannot have magic because he has no will ?
