Ples, we could also tell them that we are entering a naval battle and let them go, and then destroy their boat, gain experience, and leave.
Revan clearly hints that it's not worth fighting these four. There are more chances of survival in a naval battle. Besides, our ship is faster, we should be able to break away. We can also try to negotiate and ask them not to attack. Otherwise, they're completely crazy. But the catch is that NPCs are in charge of everything.
