Sinister question

Interesting comment from a reader Florida. Thanks HMC.

Read this question, come up with an answer and then scroll down to the
bottom for the result. This is not a trick question. It is as it reads.
No one I know has gotten it right-including me.

A woman, while at the funeral of her own mother, met this guy whom she
did not know. She thought this guy was amazing, so much her dream guy
she believed him to be just that! She fell in love with him right there,
but never asked for his number and could not find him. A few days later
she killed her sister. Question: What is her motive in killing her
sister?
(Give this some thought before you answer).

She wanted to meet him again so she hoped he would come to the funeral.
Many of the people who get this correct are psychopaths who have very little conscience. So if you know someone who did get it right, watch out. If you yourself answered correctly you have some potential as a politician.
