I agree, it makes no sense. Towards the end, Dexter began living for something other than killing - the people he loved. He didn't have the urge or need to kill anymore. He let Oliver whatever go (until he shot Deb). Despite never being around for Harrison throughout the show, he began taking the steps necessary to ensure a future where he would finally be present in the life of his son and the woman he loved. He matures, evolves, and is finally free, only to choose the life of a recluse lumberjack which is contrary to everything that happened up to that point. Dexter was never one to give up on what he wanted, no matter how idealistic it was. The only explanation is that Dexter realized he DID STILL have the need to kill and if he moved to Argentina, it wouldn't stop and Harrison/Hannah would never be free. However, this was not communicated by the writers very well if this was the intention.
