There's sure nothing wrong with taking it apart and doing it again right. The way the electrical codes are set up, so long as all junctions are in boxes and the breakers are the right size for the wires, it's very hard for even really bad connections to actually start a fire.

Once any connection starts to get loose, it gets hot, which causes three bad things to happen. The copper anneals and gets soft, which means it squishes out from under screw heads and the coil inside the wire nut loses its spring. The hot copper oxidizes, making a worse connection. And the plastic nut, insulation, or tape melts. The end result is either a totally open connection, or a short and a tripped breaker. The plastic is all supposed to be "94V0", which means it won't sustain combustion.

Every electrician has horror stories of messes he's fixed, but I have honestly yet to hear of one actually setting a building on fire. That usually takes something like somebody running an 18 gauge extension cord under their rug, plugging an electric heater into it, and then going out for dinner.
