And there's been Autobot oppression and genocide in the G1 cartoon as well.
e.g.
+ S.O.S. Dinobots: Optimus Prime authorises the creation of the Dinobots, but when they turn out to be violent brutes, he decides to imprison them in a cave - forever! So much for freedom being the right of all sentient beings eh. (although the Dinobots at the time were arguably semi-sentient)
+ Dai Atlas: _extremely_ violent and genocidal Autobot commander! Kinda reminds me of
Lancelot from Monty Python and the Holy Grail;
"He killed my auntie!" (yeah okay, Lancelot was more blindly homicidal rather than genocidal - genocide requires discriminate killing whereas Lancelot was very much indiscriminate in his destruction :D)
