Joey, if you are going to solder the wires, adding a sloppily smashed crimp to the mix is just screwing around. It serves no purpose except to waste time and money and encourage the joint to fail by adding the weight of the crimp to it.
Better to just twist the wires together and solder them, then cover them over. Faster, cheaper, simpler, more reliable.
And while you can twist wires by hand, a lineman's dyke (plier) is the tool actually designed to do that.
