I Think Kisame And Itachi.
Itachi didn't die for Akatsuki, he died for his little brother.Itachi in my opinion.
Sasori, and not because Sakura was involved but he finally go his wish, to be on with the puppets,and there was closure their, with his grandmother and parent, he came had peace of mind in a sense
Itachi didn't die for Akatsuki, he died for his little brother.
We're talking about people who were noble to Akatsuki, and also died for the organization.
