I liked Eko's character and not really sure why it was necessary to kill him off. But for that matter not really sure why Boone and Shannon had to die.

I guess the writers felt these characters stories were complete and they could kill them off and keep the tension on fans worrying that any character might be killed off at any time.

I read that the original script for the pilot episode had Jack die. And one of the reasons for this was to show that no character was safe.
