Despair is the event of complete absence or loss of hope. Needless to say, it's an unfortunate turn of events that should a character unable to cope with it, he/she would be more vulnerable to the dark side (if the character is the villain, it would be worse as despair can strip him/her chance/reason for redemption).

Everything would be worsened if he/she also an emotion vampires whom would feed on people's despair like food. In order to stop them, the hero whom facing such villains must have strong optimism that not only giving hope to the villains' victims, but also him/herself. Despair can also occured on villains' to, which would trigger their breakdown or one step for path of villainy.
