I dont think unrepentant rebel is the best description for Kira. I mean, she was part of the resistance and as such, continues in a role to bring peace and prosperity to Bajor. Vedek Beril makes a lot of sense actually. He represents peace and culture for Bajor, which is everything she has fought for. He has gotten to live a life she never could, but has always wanted. Though, dont take my word for it!
"I'll never forget the first time I saw you... that day you came to the station. You had such a serenity about you. I thought you had all the answers. It really got on my nerves for a while. Then I got to know you and I realized you were just as confused as the rest of us. You just accepted your confusion, better than anyone I've ever known. That's when I realized I loved you."
