What does this tattoo say?

[VdotMac]

I was young and dumb, when I first went into the military, and got a tattoo that was supposed to say “merciless one.” However, I had a family friend tell me that this is NOT what is on my arm. However, she’ll never tell me the definition and simply makes my arm a joke for her and her husband. Can someone let me know what this says? Pleeeeeeease?

Could you maybe post it with a clearer picture? Try to get a picture of it straight on without a glare that completely masks the first of the characters.

極惡非道 means "to do things through very unorthodox ways". It's also the name of the Japanese movie "Outrage".

More than unorthodox, it's more like evil/immoral. Connotations might be different in Japanese though, I don't know.

I just asked my Japanese wife. She says it's normally used in Japanese.

She translated it as "devilish" or "someone who can do extremely evil things" and told me to think of holocaust as an example.
