if you come to think of it Atlas isn't that evil realy he's just lost in life
do you people agree with me?
yes or no?
This version of Atlas makes him Dr. Tenma's pawn. I believe Tenma saw in Diachi's father the same arrogant attitude that he recognised in his own life. That is, Tenma created his robot for his not the robot's benefit. Likewise, Mr. Bigshot business owner's intent for his son that he passed on to the robot, was to be his heir, & take over the business. Neither cared about the needs of their sons or their robots. Thus, Tenma created a robot for the man, that would, rather than fulfill his wishes, teach him a lesson. Tenma still cared not about the robot Diachi, any more than he cared about the man for whom he built him. Once he saw his own beloved robot defeat Atlas, who should have defeated him, he became inspired to use Atlas to force Atom to 'evolve.' Atlas lost either way, whether he should become heir to the business or enemy of Atom.

The original Atlas (manga #17, volume #18) (1963 anime #26 English title "Don Tay's Infernal Machine") was built for revenge, his creator not caring about his robot's preferences. Just as Pluto was Choki Choki Abbaba's (called "King Saltan" in the synopses page) pawn.
