Who is the intended audience and from what country/hemisphere? I'm asking because the command in English can apply to one person as well as more than one. In Spanish, there are four possible translations of the command, depending on your familiarity with the audience and depending on how many you're addressing.

One of them could be,
Nunca olvides; nunca perdones.
