Anime can be as disturbing and gross as a Hollywood flick with insane amounts of Violence, Sadism, and down-right Disturbing stuff.
By no means this is an implication that these are bad Anime. Here is a concise list of all the Anime with horrendously disturbing and sickening themes whether they are good or bad is a personal preference and highly debatable.
These are quite possibly the Top 6 most SICKENING Anime ever.
Read ahead at your own discretion. You have been warned.
The first episode of Elfen Lied is bloody enough to denervate anybody's sanity. Any comments?
Higurashi is hands down the most sickeningly gory anime ever created. I could digest beyond season 1.
There's probably worse in manga
when Griffith rapes Caska in front of Guts. I bet they are gonna remove that scene from the movie compilation of Berserk that is coming out soon. Too strong for the newer generation....
Everyone talks about more current anime. But nobody ever mentions some the older series like Hnk, Genocyber, Urotsukidōji, Apocalypse Zero, etc. Many of the old school school series had even more disturbing scenes but are never mentioned....
