I don't think you have correct examples of memes not benefiting their hosts. Those are examples of them not benefiting other people who aren't the hosts. A better example would be something like martyrdom. A religion that's perfect for its host might turn out to be one that exterminates or enslaves all non-hosts - if it could somehow achieve that without sacrificing its own hosts.
