I agree.. they did plenty of running and hiding in the TV series. ROTF its more the Decepticons are running and hiding and the Autobots are searching the planet for any life signs, then going straight in for the kill.
Prime's execution of a fleeing Demolishor, and I still can't believe Ravage had his spine ripped out.
Cold-blooded (in a robot?) murder in a Decepticon makes sense. They're supposed to be the bad guys that tried to enslave the planet a number of times in the cartoons - this is what the Autobots should protect against, not arbitrarily exterminate.
