Movie Plot Holes and Paradoxes

Transformers The Allspark creates killer Transformers

So in the critically adored Transformers (well adored by the standards of the series), the Allspark, the creator of Transformer life, is used to bring everyday human mechanical objects into life. These same newly created Transformers then proceed to go on a murderous rampage straight away, suggesting that being evil is in the Transformers nature. Does this make Optimus Prime and his Autobots some sort of weird hippy peace living cult then? And if Transformers just want to kill, then we should atempt to destroy them not work with the aliens. This is not the Transformers I was brought up on.
