Well actually, his was more like "you're either a slave in one of the three highly dystopian pessimistic stellar empires trying to rebel or you're somebody so bad you could actually be our enemy."

Well, they would be formed for different reasons, depending on the species in them. For example, you might have one alliance formed around a species seeking power, but one of its allies joined because it wants to get revenge for a grave injustice done by someone else. Then the other alliance might have formed in the interest of mutual protection, but have one of the allied races join because it lusts for battle and thinks that this alliance will give them more opportunities to kill.
