In ST:DS9 4x15 "Sons of Mogh," Kurn attempts Klingon ritual suicide so as to enter StoVoKor by dying with honor. By the end of the episode, Worf has his memories erased and he is taken in by a family friend as Rodek, son of Noggra.
As a Klingon, I don't get how Worf was okay doing this. More to the point, how does a Klingon enter StoVoKor? Will he enter as Kurn, or as Rodek? Does changing his entire identity - and that only in a medical way, as there was no Klingon ritual they undertook to change his identity - change who he is when he tries to go to StoVoKor?
How did this ultimately help Kurn with his ultimate concern of entering StoVoKor?
