7. Mr. Eko - Lost
This one still hurts a little bit. Introduced in the second season as one of the survivors from the tail section, Mr. Eko quickly became not only the most interesting character from that group, but one of the most interesting in the overall show. Bernard was a supporting character and it was nice to see him on occasion, but occasional appearances was all he was ever going to make and if you watched the show you are well aware of what happened to Anna Lucia and Libby. It was brutal; some say awful and other say awesome but no matter what camp you fall into you were probably happy that it wasn't Eko. Though he entered the series as a rather quiet man, we soon came to learn that the apparent priest was hiding a dark and violent past. It was hardly a surprise that there was more than meets the eye when it came to Mr. Eko, but personally I wasn't expecting him to have been such a bad person in his life before the crash. In order to spare his little brother, the young Eko killed a man as ordered by a group of guerrillas in his native Nigeria. Due to his recruitment into the group he grew up to be a vicious drug baron, whilst Yemi his young brother became a priest. His decision as a boy to sacrifice his innocence for his brothers is what eventually killed Yemi, as he was gunned down after Eko forced him into one of his criminal plots. He soon took Yemi's place as a priest, before taking a seat on Oceanic flight 815. Though most of us would probably jump at the chance to live in Hawii, seemingly it's not for everyone Eko's portrayer Adewale Akinnuoye-Agbaje asked to be written off the series. The actor's desire to leave the show led to an abrupt exit for his character. Mr. Eko met his maker in the form of the smoke monster, who brutally mauled the faux-priest. The most frustrating thing about this exit was the fact that there was clearly so much more story to tell, so many places for the character to go. Instead he was bashed against some trees and it was all over.
