Is it true that Alice in Wonderland was actually a...?

a graphic story. Graphic such as; blood, gore, violence, etc.. and that Disney just interpreted in more of a child setting? My friend says Alice Madness [the video game] has the right idea of what the original story was about, not all that colorful **** they show in the Disney version. So if the original story of Alice in Wonderland was really more of a scary-type, what was the name?
