ok then people, explain to me how Future Flash has evidently killed the present day (or 5 years from now) Flash and hasn't disappeared? I mean I do remember from Back to the future that if you do something that affects your past, it can have dire consequences, so surely future Flash cannot kill his past self without ceasing to exist? Confused.Com!!

@bezza: look up Hyper Time it's on old concept that DC came up with after they decided to get rid of the multiverse for a few years. As I understand it explains how Barry can kill himself in one timeline with out affecting himself or the rest of the Futures End time line. Remember Barry was alive and well in the Brother Eye future so he can't die in the five years later era. Also just because time travel works one way in the Back to the Future universe doesn't mean the same rules apply to the DCU.
