But even pirates have friends. Note that the Generic Pirate is the only ID that has no allies and many enemies. Liberty Rogues are specifically allied with Outcast, Molly and Lane Hackers. In fact, most pirate factions are allied with the Outcast. The one thing they have in common is that they are the downtrodden rejects of their systems. They are the ones who are oppressed by their governments and forced to live in exile. They are more than just pirates for cash, they are also freedom fighters and revolutionary soldiers.
Being a pirate does not automatically mean everyone is a target. Pirates tend to share their loot. Some history of pirating in the Americas proves that they were among the first true democracies. Pirate ships were notoriously democratic. Every member of the crew had a say in what missions to take on. And many ships roamed together to take on larger targets. After the battle, the pirates would take the loot and divide it amongst themselves - and typically spent it faster than they took it.
