INTO JAPANESE
それは優れていたので、彼を殺した
BACK INTO ENGLISH
So it was better that he killed
INTO JAPANESE
それは優れていたように彼を殺した
BACK INTO ENGLISH
It is better killed him as though they were
INTO JAPANESE
それは良い、あたかも彼を殺した
BACK INTO ENGLISH
It is good, though he killed
INTO JAPANESE
それは良い彼を殺したが
BACK INTO ENGLISH
It killed him good
INTO JAPANESE
それは良い彼を殺した
BACK INTO ENGLISH
It killed him good
