Anyone else notice both are now responsible for purges...both came back to life in the temple and both were involved in the same shooting (Sayid and Ben on opposite sides of it). Sayid was also shot by Ben's dad.

Sayid hated Ben more than anyone did (except for maybe Jack) and that hatred drove him to eventually become him.

As I'm typing this I'm also realizing that JACOB and MiB are ALSO both responsible for purges...assuming Richard was speaking for Jacob when he was pulling Ben's strings.
