कामवृत्तः lustful, कापथम् evil path, आश्रितः resorted to, राजा king, सद्भि: by the good people, अमात्यैः by ministers, सर्वथा always, निग्राह्यः हि should be stopped, निग्राह्यः prevent, न निगृह्यसे not prevented.

Good ministrers should always prevent a lustful king from taking resourse to an evil path. Why were you not stopped, even though you deserve to be checked.
