YOU SAID:
i must murder everyones mothers and fathers
INTO JAPANESE
私はみんなの母親と父親を殺さなければなりません
BACK INTO ENGLISH
I have to kill everyone's mother and father
INTO JAPANESE
私はみんなの母と父を殺さなければなりません
BACK INTO ENGLISH
I have to kill everyone's mother and father
That didn't even make that much sense in English.
