[DBZ:Android saga] Why did Dr/ Gero go past android 16. Yes he said he was not complete but he is A. Far stronger than 17 and 18. B. Level headed and obedient. C. wants to kill goku. Sure he wasn't done but why not just continue to work on him instead of making 17/18/useless 19

and cell for that matter.

WAS he obedient?  Gero was dead so he just went with it.

Maybe he didn't follow Gero's orders, and after Android 8 Gero wanted to be sure things would go as planned.

Also he had that bomb in his body that he could choose to activate at any time.

Not following orders + having a ridiculously powerful bomb in his body = dangerous, do not activate.
