No Fear of Evil in Chinese / Japanese...

不怕邪惡 literally means “no fear of evil” in Chinese.

Chinese grammar and word order are a little different than English. 不怕邪惡 is the best way to write something that means “fear no evil” in Chinese.

The first character means “not,” “don't” or “no.”
The second means “fear.”
The last two mean “evil” but can also be translated as sinister, vicious, wickedness, or just “bad.”

悪を恐れない is “Fear No Evil” in Japanese.

Japanese grammar and phrase construction is different than English, so this literally reads, “Evil Fear Not.”

The “evil” Kanji can also be translated as “wickedness.”

In Japanese, 無心 means innocent or without knowledge of good and evil. It literally means “without mind.”

無心 is one of the five spirits of the warrior (budo) and is often used as a Japanese martial arts tenet. Under that context, places such as the Budo Dojo define it this way: “No mind, a mind without ego. A mind like a mirror which reflects and dos not judge.” The original term was “mushin no shin,” meaning “mind of no mind.” It is a state of mind without fear, anger, or anxiety. Mushin is often described by the phrase “Mizu no Kokoro,” which means “mind like water.” The phrase is a metaphor describing the pond that clearly reflects its surroundings when calm but whose images are obscured once a pebble is dropped into its waters.

This has a good meaning in conjunction with Chan / Zen Buddhism in Japan. However, out of that context, it means mindlessness or absent-mindedness. To non-Buddhists in China, this is associated with doing something without thinking.
In Korean, this usually means indifference.
