If things are super-deterministic then things are not realistic.
Bell assumed realism because he needed to be able to talk about what
the results of a experiment would have been if different choices
were made, but if things are super-deterministic then different
choices could NOT have been made. So Bell assumed realism.

It doesn't matter what Bell personally thought was believable or
unbelievable, Bell proved that if realism and locality and high
school algebra and trigonometry are valid then his inequality can
never be violated. But experiment showed that Bell's inequality WAS
violated, therefor at least one of Bell's assumptions is wrong and
either realism or locality or high school mathematics MUST be wrong.
And I don't think its high school mathematics.
Bell assumes unicity of the outcome of measurement. EPR too.

All those interpretations are still in the running just as MWI is,
but theories that are both realistic and local are not.
