Shanks is more brutal than Kaido or BM. He has now on two occasions been shown attempting to kill crews who had already surrendered or were escaping.
BM and Kaido on the other hand often try to recruit those who challenge them. Shanks offers his challengers no such proposition. He doesn’t take slaves or captives. He just destroys his enemies.
In a way he reminds me of a more mature version of Captain Kid, who similarly takes pleasure in destroying his enemies, even if they beg for mercy. The obvious difference however, being that while Kid can be erratic and kills others for simply laughing at his dreams, Shanks only destroys those who hurt his friends.
