YOU SAID:
I will NEVER kill my parents
INTO JAPANESE
私は決して両親を殺しません
BACK INTO ENGLISH
I will never kill my parents
INTO JAPANESE
私は私の両親を殺しません
BACK INTO ENGLISH
I will not kill my parents
INTO JAPANESE
私は両親を殺しません
BACK INTO ENGLISH
I will not kill my parents
That didn't even make that much sense in English.
