Actually Toothless could tone down his firepower to not significantly hurt humans, just knock them down or knock them unconscious and he could also tone up his firepower to destroy battlements. So I do think that the Screaming Death would crush Toothless like the black rat he is. 2 of Toothless'  attack's "barely put a dent" in the screaming death and the Night Fury has a shot limit of 6.
