This is in sharp contrast to Salazar, who broke the deal when he saw pirates? Negotiation? Killing Barbossa several times scared him, but killing his crew was in stark contrast to Beckett sitting down to drink coffee. In addition, salazar is still a Spanish navy, which indirectly shows that only killing people will eventually decline.
What is Beckett's ambition, killing pirates? Obviously not. He wants to rule the ocean, so he wants to control the flying Dutchman, he wants to control the Black Pearl and Jack, and he wants to control the pirates.
He said verbally that he would kill all the pirates and most of them, but in fact, he wanted Jack to surrender. Jack said he would give him all the pirates, and he smiled. It can be seen that he said he would kill pirates only verbally. Of course, his fleet is capable, and he just wants to beat the pirate king all over the world. Even if it wins, the strength of the East India Company will drop sharply and become the deadly enemy of pirates all over the world. This price will be high, and the East India Company may be replaced by a declining empire. Pirates all over the world can't be killed, and the East India Company doesn't have to go to so much trouble, but pirates can be used, as evidenced by Beckett's previous Amnesty authorization.
So many people say they can win, why not fight? The question is, what if he wins the pirates? His ambition is to subdue the pirate king, and fighting is not his option at all. He wants Jack to surrender and the Pirate King to surrender, so that he can rule the ocean. Finally, when the Black Pearl and the flying Dutchman came at him, his dream was shattered.
This is the reason why this film exaggerates the plot. Some people say that we should carry forward the fine tradition of pirates (escape or surrender). Jack refused this time. There is no such tradition. This time, we will not run away or surrender. This time, we chose to fight for a reason. It is a tradition of pirates to resist the oppression of rule. If the pirates choose to surrender, they will return to the way of life under the oppression of the rule before becoming pirates, and respond mercilessly to the beginning of the third part, why the oppressed people sing pirate songs and summon the pirate king.
