That's too wide a net to cast. A gene that benefits the entire species
does not have any feedback to spread. The math for it to spread means it
must save more copies of itself than are lost.

You are getting close to the models constructed by the late William
Hamilton (Dawkins cites him a lot.) You don't initially even need memes to
see how this evolved. People take great risks for those they are related
to. Since we are not all that good at determining exactly who we are
related too, psychological mechanisms bias us to take risks for those we
grew up around--and in tribal days most people in the tribe were related so
taking risk and even being killed let genes for that behavior spread.
Through capture-bonding and reward-bonding, people relate to people in a
(meme driven) cult as if it were their tribe. As a result you can expect
them to take actions which risk them getting killed. Thus a genetically
based mechanism has been hijacked into the "service" of a meme.
But as a guess, for every person who is killed or neutered by a cult, tens
to hundreds of relatives are saved from burning buildings (at considerable
risk and sometimes death to those who rescue people). So in spite of
people taking insane risks, killing themselves, or whacking their nuts off
(or both for the Heaven's gate cult) the genetic bias for taking extreme
risks for family and cults is likely to persist.
The western cultures are very different from the one in which we evolved,
the cultures of the middle east are much closer to the tribal way of
life. It would be a worthwhile study to see how the genes of the hijackers
fair. I know that in Israel those who commit suicide benefit their
families by increased prestige. I don't know if that turns into enough
more offspring from their relatives to make up for their genes being lost,
but I would not be surprised if it did.
