How do you feel when someone bad/evil/corrupt gets whats coming to him? You can read about it in the news for instance. Take those 2 Tsjarnev kids for example, when one of them got shot? Or headlines such as:
"Seph Blatter stabbed to death by activist"
"Serial Child Rapist becomes bitch in jail"
"Animal Abuser torn apart by pitbulls"
Or take non-fictional

Example 2:
A bit overexaggarated ofcourse, but you know what i mean. News paper articles that make you go "good riddance" or "Karma is a bitch"..
Do you become happy reading them? Indifferent? Neutral?
