The four boys didn't try to create the chaos, it just naturally followed them. They were just waiting for rescue and trying to have a little fun along the way. Of course, if they made some money that was even better.
Hardly any of the adults around them agreed with their idea of fun though. They claimed they were the ones battling the chaos following the boys. The boys didn't really intend for those battles to start a war between several planets, pirates and sex slavers. It just happened.
