The Serial Killer Test..
It is a story about a girl. While at the funeral of her own mother, she met a guy whom she did not know. She thought this guy was amazing, so much her dream guy she believed him to be, that she fell in love with him there but never asked for his number and then.....
A few days later the girl killed her own sister.
Question: What is her motive in killing her sister?
This was a test by a famous American psychologist used to test if one has the same mentality as a killer. Many arrested serial killers took part in this test and answered it correctly.
If you have heard this question before and know the answer, please don't spoil it for everyone else. I'll give the answer in a few days.
