Some people might try to make amends in other ways. They could try to do good deeds in the name of their BFF, like donating to causes their BFF cared about or helping the BFF's family. However, the guilt will always be there to some extent, and it's a burden that they will carry for the rest of their lives.
I'm not sure if it's a true story as there could be many fictional or exaggerated accounts with such a title. It might be a very disturbing and tragic claim if it were true, but without proper sources, it's hard to verify.
It could be due to a fit of uncontrollable rage perhaps caused by a long - simmering feud over something like money or a romantic interest. Maybe there was a deep - seated jealousy that had been building up for a long time.
The killer should face life imprisonment. Taking someone's life, especially a close friend, is an unforgivable act and they should be removed from society to ensure public safety.
It could be a case of self - defense gone wrong. Perhaps the person felt threatened by their BFF in some way, but in the moment of trying to protect themselves, they ended up taking it too far.
The motive could be jealousy. Maybe there was something the killer wanted that the BFF had, like a relationship or a job opportunity. It's a tragic situation.
Some people might turn to religion or spirituality. They may believe in the concept of atonement or redemption. By praying, doing penance, or following religious teachings, they hope to find some peace within themselves.
