It is thus worth noting that deliberately burning people to death is achievable – and deliberately achieved – in all sorts of other ways:

"Living Under Drones: Death, Injury and Trauma to Civilians From US Drone Practices in Pakistan", NYU School of Law and Stanford University Law School, 2012:

The most immediate consequence of drone strikes is, of course, death and injury to those targeted or near a strike. The missiles fired from drones kill or injure in several ways, including through incineration[3], shrapnel, and the release of powerful blast waves capable of crushing internal organs. Those who do survive drone strikes often suffer disfiguring burns and shrapnel wounds, limb amputations, as well as vision and hearing loss. . . .

In addition, because the Hellfire missiles fired from drones often incinerate the victims' bodies, and leave them in pieces and unidentifiable, traditional burial processes are rendered impossible. As Firoz Ali Khan, a shopkeeper whose father-in-law's home was struck, graphically described, "These missiles are very powerful. They destroy human beings . . .There is nobody left and small pieces left behind. Pieces. Whatever is left is just little pieces of bodies and cloth." A doctor who has treated drone victims described how "[s]kin is burned so that you can't tell cattle from human." When another interviewee came upon the site of the strike that killed his father, "[t]he entire place looked as if it was burned completely, so much so that even [the victims'] own clothes had burnt. All the stones in the vicinity had become black." Ahmed Jan, who lost his foot in the March 17 jirga strike, discussed the challenges rescuers face in identifying bodies: "People were trying to find the body parts. We find the body parts of some people, but sometimes we do not find anything."
