A broken clock is right twice a day, evil can do good, and sometimes the butler actually did it. One example is not a pattern.
Too bad for the poor unicorns then. They'll have to bear the shame of killing anyone not a virgin female who approaches them, according to folklore, and if you follow the more ancient stories they're far more vicious.
Point being, unicorns are evil bastards
Let's face it, who is more numerous: People who lived in medieval Europe and thought unicorns were bastards, or the sum total of people who lived in medieval Europe and considered unicorns to be pure plus 99% of the people in Europe, America, Australia, and so forth over the past few centuries who considered unicorns to be a paragon of goodness?
and it doesn't really matter anyway since I'm transforming into a machine god planet.
Who has a name suspiciously similar to a mythical creature which is associated by almost everyone with goodness. Which I'm sure is just a coincidence, as is the fact that Unicron created a bunch of knights with shining chassises.
The first type. *pessimist*
Also, it was actually Primus that created the transformers. Unicron eats universes because creation offends him.
