desatanizar

A rare, almost exclusively religious or rhetorical coinage meaning to remove a "satanic" or demonized characterization from something — used when reframing an idea, practice, or group previously condemned as evil. It's marginal vocabulary, appearing mostly in religious or cultural commentary.

• El autor busca desatanizar ciertas prácticas paganas. — The author seeks to de-demonize certain pagan practices.
• El documental intenta desatanizar la imagen del rock en los años 80. — The documentary tries to shed rock music's 'satanic' image from the 1980s.
• Algunos teólogos han intentado desatanizar esa figura histórica. — Some theologians have tried to remove the 'satanic' label from that historical figure.

This is a marginal, rhetorical coinage rather than standard vocabulary — a learner is very unlikely to encounter or need it outside specific religious or cultural-critique writing.
