A compressor is an extremely useful tool, especially for bass. While you dont exactly need one, it sure is awfully nice to have one.
Probably the most important reason to compress the bass signal is that it greatly facilitates getting the bass to be heard properly when combined with other instruments in a mix.
Without compression, the bass tends to fluctuate between being too quiet in the mix, so that it cant be heard very well, and being too loud, where it overpowers the other instruments and vocals. Compression automatically evens out the volume.
