Multi electron interference in double slit experiment

Electrons have negative charge, and therefore repel each other. That should mean that their position, and momentum probabilities should get skewed away when in the presence of some other electron. I.e....

Does wave-particle duality rely on accepting the Copenhagen interpretation?

If you're a scientist that subscribes to the many worlds theorem, does that mean you do not accept wave particle duality? Seeing as MW postulates that the wave or particle form has always existed that ...

Would the double slit experiment still yield the same results if the electron were travelling really slowly?

And I mean really slow. I don't know how this would even be done, but just a thought experiment. To explain why I ask this, the way I understand the phrase "we can't know the momentum and position ...
