Killed Members
Other members kill each like how Kakazu kills every partner he has except Hidan since both him and Hidan is immortal. Members are allowed to kill each other and some even say that they were killed by the enemy!

Ex-Members
Most Ex-members are killed because they have information on the group. Kamai and Zamui had a complicated past together and stabbed each other with a Kunai Knife in the heart and both died together. Check episode 98 Kamai and Zamui for more info.
