In The Hunger Games, by Suzanne Collins, evil is seen most in the Capitol because they are responsible for sending twenty-four innocent children into the Games each year. After District 13 rebelled against the Capitol, they became worried about being defeated completely and created the Games in order to keep the other Districts from following District 13 and revolting. The tributes from each District all seem to feel insecure with their strengths and abilities because they know that they are about to be sent into an arena to literally fight for their lives with only one tribute coming out alive.
In Lolita, by Vladimir Nabokov, Humbert Humbert has insecurities because he lusts for nymphets (girls that have not quite hit puberty) and is unable to control his actions. When he falls into his temptations, it causes his hormones to go haywire which leads him to lash out against his victims. His first love, Annabel Leigh who he had a strong connection to, later died which resulted in his strange desire for nymphets. He and Annabel Leigh did not have sex before she died which made him long to have that childhood feeling that she gave to him. He goes through life trying to find that glimpse of love that he once had with Annabel Leigh, and he finally had the chance when he meets Dolores (Lolita). Both Humbert and Lolita used one another to get what they wanted; Humbert used Lolita for sexual favors and in return, Lolita was allowed to join a play and was given money and clothes.
