Bacca is a cruel and selfish pirate who will do anything to get what he wants. However, in his own view, he simply does what he wants, and has therefore never done anything wrong; according to him, this follows his creed of "freedom".

He's been a troublemaker since his childhood, and has committed many crimes. He shows no hesitation in destroying his own hometown or in killing the townspeople so long as he can get what he wants, and shows no remorse in hurting his own father.
