Exactly Rodney-2187, what if the Mandalorian went around just being a bounty hunter, capturing, evading and collecting his prize. That would get really boring after awhile.

His character grew as the story went along. We don’t know what will happen to Boba Fett, but he now has many strong allies, each with their own strengths, all of them coming together to defeat the bad guys.

All of this is possible because he didn’t just kill everyone he came across, he gave them a choice. These choices bring opportunities for his entourage.
