YOU SAID:
I am become death, destroyer of worlds.
INTO JAPANESE
私は死、世界の破壊者となっています。
BACK INTO ENGLISH
I have become death, the world of the destroyer.
INTO JAPANESE
私は死、駆逐艦の世界となっています。
BACK INTO ENGLISH
I have become death, the world of the destroyer.
That didn't even make that much sense in English.
