The Evil That Men Do is also the title of several books.Well I can make you a list of Maiden songs that share titles with books and narratives:
Then some with obvious and stated inspiration and other tidbits:
William Shakespeare - Julius Caesar (The Ides of March, The Evil That Men Do)
Cried, are you aware of the plots of (if possible) all these books? Then we could see/rule out if the lyrics of the song have anything to do with these.The Evil That Men Do is also the title of several books.
There's also the Charles Bronson film, of the same name, from 1984...Cried, are you aware of the plots of (if possible) all these books? Then we could see/rule out if the lyrics of the song have anything to do with these.
If not, then first I could search for Maiden interviews and if I can't find anything clear, then we could do an attempt to dig up these plots.
I came up with these these nine songs, based on literature.let's see if we can make a complete list of books, which were direct sources of inspiration for Maiden (so no works where films were the inspiration instead of the books they were based on).
