After reading all the adaptations of ROTF and DOTM (comics, novels), it gave a lot of backstory on Megatron and seemingly how many of his actions were justified in some sense. In the end, he's still trying to repair Cybertron and his race, at the expense of Earth. I thought it was cool how they made a truce in the adaptations but I didn't like how Optimus just killed him in the movie. I was thinking that maybe since Optimus is taking the fight to the Creators, that the entire transformers race would be in danger and force Optimus and Galvatron to join forces so that Galvatron isn't the main bad guy as much. Cause I really like when a cool bad guy gets redemption instead of some lame defeat because the plot calls for it.
