The beginning of the movie has the Autobots hunting down and killing Decepticons that are hiding on Earth. My question is why? Megatron is dead (at the time) and I would think the Autobots would want peace not killing every last one of them. I know the Decepticons are evil but it seems they can be redeemed. Jetfire changed sides in the movie as did Wheelie (kind of) so we know it is possible. I would think that Optimus Prime would want peace and to reunite with as many of his kind as possible. Megatron is gone so wouldn't it be the ideal time? I just don't picture the Autobots as a "kill them all!" type group. Thoughts?
