No worries Scarlet, remember it is only somebody's strange fantasies put to paper.   If dragons like that actually existed virtually everyone over the age of seven understands that a few humans with swords and spears couldn't possibly kill one of that size, and if it were ever attempted, the dragons would simply exterminate them. .   I think the artist may have been playing waaaaay too many juvenile video games to come up with something so silly.  Perhaps it is an illustration for  a children's fairy tale, for surely no thinking adult could ever take such nonsense seriously.  Just laugh at the idiocy of it rather than be outraged.
