[Star Trek] Why does the Borg queen exist?

I've been watching both TNG and Voyager and I still don't get the Borg queen.

She isn't there to represent the Borg because she makes big decisions but she kinda is made as a representative of the collective in TNG. Why does she make big decisions instead of the collective doing it? Why does she act like she has feelings? Why does she have feelings in the first place? What's the point of the hive mind if she can say fuck it and do her own thing? Why is she even an individual?

What's the point of having something that's considered a force of nature, a species that became what it is now so long ago no one remembers what they were in the first place and giving them a face in Voyager and an evil one at that?

I'd like for someone to explain this at least in a few sentences because watching Janeway and Seven tag team vs. Queen and a few evil drones match is kinda annoying at this point.

At some point in time, the Collective grew too large to function as a simple hive mind.  Thus they had to implement a "Command Node" structure which managed portions of the Collective.  The Queen we see is most likely one of many, all interconnected and sharing one mind, controlling their own little portion of the Collective.
