At least in German the word "to apologize" ("sich entschuldigen"; although this translation, though often used, is considered to be impolite; if you are interested in the details read http://www.spiegel.de/kultur/zwiebelfisch/zwiebelfisch-entsc...) has "Schuld" ("guilt") in it. This implicitely states the belief that there exists a concept as guilt, which I don't, since I don't believe in free will.
