adjective
sordid
SOR-did/ˈsɔːrdɪd/
Filthy and degraded in condition.

Etymology
Being dirty supplies an image for moral baseness: conduct can be filthy without involving literal dirt. The Latin adjective already covered both physical foulness and the figurative sense of being vile or base.
In context
