Evidence Quote

if you're a merchant ship being attacked by a pirate ship and you resist the Pirates attack the Pirates are outlaws they can do anything they want to you... this is important for pirates because in order to cash in on the kind of greater scare factor of being a pirate then you need to somehow communicate that you're an outlaw
