After Christianity came to Finland, the reputation of Lempo worsened: it is portrayed in the folklore usually as an erratic spirit, as love can be capricious, even dangerous, and it could even take control of a being and turn them to destruction.
The words "lempo" and "hiisi" are also used as very mild swear words in the Finnish language. Piru is a slightly stronger swear word. This is also the work of Christians, they were not originally bad words.
