Hi GluonBall, that's entirely possible. Right now there's only the English locale file, but adding other locale files can be added if someone provides the translations.
I'm currently reworking larger parts of the mod structure which will affect locale handling. I had planned to go for the German translation afterwards.
Let me know if you want to translate things yourself, it's not too complicated. You'll find a locale/en/Pacifist.cfg file in the Pacifist.zip in your mod folder. In there you have the English translations. If you create a locale/de/Pacifist.cfg with the German words, it should automatically be used.
Let me know if you need more details.
