I like writing dark characters. Evil, amoral jerks are fun to write, because they do things the reader doesn't expect. I am not so good at the moral, upstanding characters. However, sometimes I will be writing a character, fully aware that the are dark and evil, and...the character does something, says or thinks something that makes me horribly uncomfortable. I've had two characters (so far) take me to places I was not comfortable going. Rather than continue writing, I dropped the story and now sort of refuse to play that character. I am bringing this up now because of an interesting twist. First I shall explain the history. The first character who took me somewhere too dark for me was an alien villain, who, while raping the protagonist, decided he wouldn't mind eating her afterwards - or during. I was so thrown I still refuse to write the character into any story, or even use the same names/different character in any story. However, a few days ago, I intentionally created a young female cannibal (recovering cannibal, actually, its been one year, ten months and three days since she last ate human flesh). I like this character, and, after creating her, I spent the whole day (and half the night) thinking about her, playing through potential scenes in my head, getting to know her. I ....don't know why I might be comfortable with a human eating another human, but writing an alien considering eating a human is disgusting. What is so very different about these characters that one is fun to write and the other is...sickening? Has anyone else had a similar problem? Either writing a character who ended up being worse than you expected/could handle, or writing a character you didn't like, and then ending up creating another similar character who you did like?
