I dont think so, i mean really. imagine you are a gigantic robot, whats more important your own planet or the planet earth ?? I mean almost everybody would try to safe his own race and own planet before he saves another world. thats also why i prefer decepticons over autobots, to be autobots are tratitors to the cybertronian race, optimus destroyed the most important thing of the cybertronians, the allspark. thats why i see them as traitors. I think many people may disagree with me, but thats my oponion. OI dont find it logical though that sentinel and the decepticosn want humans as slaves ( though to be honest, what sense makes it for 20 or 30 feet tall robots to have such tiny slaves, i am sure one single tf can do more than 20 humans together in one day. so that doesnt make big sense to me.
