Initially Megatron (aka Galvatron and C-81) was not the viciously brutal leader of the Decepticons: he was once brothers-in-arms with Optimus. But Megatron resented his comrade, knowing he was a Prime. This anger allowed The Fallen to ensnare him and led to the revival of the Decepticons. Even without The Fallen, it's not hard to imagine that Megatron would have tried anything to rid himself of Optimus.
