Check out this post from the Emotional Differences Collaboration on the one of the anime Amino communities. The collaboration is exploring the different emotions felt by different anime characters all based fan fiction. The fan fiction that I read that won first place was the emotion of Immorality. The immorality were examples of the characters Obito from Naruto Franchise, Lord Aizen from Bleach, and Lelouch from Code Geass. I strongly suggest to least try to have s glimpse at the creators work and give them a like for their effort.
