You're very welcome. I also like this translation best. I'd take it as a statement of acceptance. Like someone accepts that they committed some sins in the past but it's now exactly that, in the past, time to move on and probably do better.

But's this all in the gray area, one can understand it differently. Like that person actually cherish that sinful time. I doubt you can make a crystally clear statement with just 2 words, that is true for any language. I guess what's more important is that YOU know what that means and you can always explain it to those who took it wrong. Also, you can try and "solidify" this statement with a good picture, it's a tattoo after all. But that's up to you
