The entire Android Saga is Bulma's fault anyway.
- Had she not interrupted Piccolo's fight, he would have taken out Android 20 before 16, 17 and 18 got reactivated.
- Had she, at any point, remembered that her dad totally knows the one guy with android development history, they could have killed him years ago.
- Had she not given Krillin, of all people, the remote detonator, then Androids 18 and 17 would have been taken out.
- Had she not taken out 16's bomb and then not told him, Cell would have been destroyed (maybe) slightly earlier.
- Had she invented a time machine that actually works properly, Trunks wouldn't be late to every important event.
This is mostly correct. Goku would have been against the whole kill Gero thing (they had considered gathering the Dragon Balls to find Gero and kill him off but he nixed it because he hadn't done anything wrong/he wanted to fight androids.
17 was already taken by the time Krillin got the remote. Spot on about the other two. Trunks really could have just shown up a week early for the Android attack so that's partially on him.
