So stop doing it. That name turns up much more often in English language media that it does here in Norway. Here he was to a quite large extent treated as a common criminal, a murderer.
That said, I can certainly attest to the word being commonly used in a host of other languages besides English, including Slavic ones. Perhaps it is the case that it is not frequent in Spanish-speaking societies.
