Continued use of soapy water strips the protective cuticle off of plant leaves - this can result in the leaves burning. The occasional use of soapy water to kill small insects such as aphids, scale and mealy bug is okay - as long as you don't do it too frequently.

The long term effects of soapy water on the soil are not good, this causes a layer to build up on the soil and also effects osmosis in the soil - which can cause plants to deteriorate and die
