DS - except that there are almost always survivors from a napalm attack in addition to the deaths.
These have life-long scars and disabilities from the burns (after taking weeks/months in agony to heal) - those that don't die from their burns after days/weeks/months in agony.
Yes, it is a bit hypocritical to pick one method of killing/maiming to ban but not touch the others - but fire is one of the methods that inflicts the most suffering on both its survivors and those who die slowly from it.
