I'm... Not really sure. It's definitely a debuff for the individual, but for Martian society as a whole it allowed them to develop and grow as a people. So it's a mitigating influence?
I recall Burning Martians took their shapeshifting to a whole new level but were absolutely monofocused on their desire to the exclusion and often detriment of other Martians.
Esuna or Dispel might work... But I'm more tempted to consider the burning Martian a regressive dead-end for the species. An echo or genetic memory after however long it's been sealed away, rather than a natural state for the Martians at this point.
It's... Honestly just too complex to say either should work, so I'm going to settle on neither. Maybe a ritual of some kind to embody the ideal strengths of a species could reawaken it.

accessory and has to pull out his Magic Wellness Stick to beat some sanity into people.
