Of course, perhaps the most unnerving sort of manga are those about people whose minds and hearts become twisted enough to kill their fellow men, the sort of person worth of the moniker "monster."
MONSTER, by Naoki Urasawa. First published in 1994 and first published in North America in 2006.
PLOT:
Dr. Tenma was a skilled neurosurgeon with a promising career. He was working with some of the best surgeons in Germany, as well as a promising engagement to the daughter of the director. Everything was looking up for him...until Tenma defies his superior’s orders and operates on a gravely injured young boy instead of the mayor of the town.
This single decision costs him his cushy position and his
fiancée, and the former is only saved because his superiors die from poisoning. Years later, Dr. Tenma is the head surgeon, but he suspects that the recent chain of murdered childless couples may be tied to the young boy he saved so long ago.
