Soaps often have a chemical in them that make them antibacterial.
One is called triclosan, but there are many others.
At high concentrations, triclosan acts as a biocide (killing the bacteria) by interacting with multiple cytoplasmic (liquid inside the cell) and membrane targets (the outer circle of the cell that keeps it intact). However, at the lower concentrations seen in commercial products, triclosan appears bacteriostatic (which stops their reproduction), and it targets bacteria primarily by inhibiting fatty acid synthesis.
Interesting question! Not all soap kills bacteria, only the soaps with a special chemical in them that sticks to the bacteria and stops them multiplying. This is why soap should never be eaten as it could damage our insides by sticking to us!
