Not a physicist at all but I'd offer the following thoughts on the question of "why":
- Take a neutron, pull out an electron (and an antineutrino), and you're left with a proton.
- Asking why protons and electrons are so different is a little bit like asking why hydrogen and iodine have exactly opposite charges even though iodine is so much more complex: they're made of different things
