The pressure of the water coming out is tremendous, so without (much) help the hose would be very hard to control and people could be in potential danger.
If firefighters didn't have help holding the hose, it would be extremely difficult for one person to control and maneuver the powerful stream of water. The hose could become uncontrollable, making it harder to effectively extinguish the fire. Additionally, firefighting requires teamwork, and without assistance, the overall effectiveness of the firefighting operation could be greatly diminished.
People would be killing each other and stealing things and things would be destroyed and so would the world because police and firefighters prevent these things.
