YOU SAID:
no one knows what is like to be the bad man
INTO JAPANESE
誰が悪人であるかを知らない
BACK INTO ENGLISH
Do not know who is the bad guy
INTO JAPANESE
誰が悪者かわからない
BACK INTO ENGLISH
I don't know who is bad
INTO JAPANESE
誰が悪いのか分かりません
BACK INTO ENGLISH
I don't know who is bad
That didn't even make that much sense in English.
