YOU SAID:
i will kill me in this day
INTO JAPANESE
私はこの日に私を殺すだろう
BACK INTO ENGLISH
I will kill myself on this day
INTO JAPANESE
私はこの日に自分を殺すだろう
BACK INTO ENGLISH
I will kill myself this day
INTO JAPANESE
今日私は自分を殺すだろう
BACK INTO ENGLISH
Today I will kill myself
INTO JAPANESE
今日私は自分を殺すだろう
BACK INTO ENGLISH
Today I will kill myself
That didn't even make that much sense in English.
