There are several potential motives. It could be due to a mental disorder that made her lose touch with reality and act violently. Or perhaps she felt threatened in some way and thought killing was the only way to protect herself. It's also possible that she was influenced by someone else who pushed her into committing these crimes.
One possible motive could be money. Maybe she was after an inheritance and decided to eliminate those who stood in her way.
Jealousy might be a motive. For instance, if she felt that another family member was getting more attention or love, she could have lashed out. Another aspect could be mental illness. If she had an undiagnosed or untreated mental disorder, it could have led to violent behavior.
No, it's not. Killer Grandma is likely a fictional creation for entertainment purposes.
In some cases, mental illness can be a factor in a 'killer among friends based true story'. A friend who is suffering from an undiagnosed or untreated mental disorder may have delusions or hallucinations that lead them to believe their friends are a threat or are somehow 'evil'. This could cause them to act out violently. Also, a sense of power and control can be a motive. Some people get a thrill out of having power over others and may see killing their friends as a way to assert that power.
Mental illness is a significant factor that could be a motive in a 'killer granny true story'. An undiagnosed or untreated mental disorder might lead her to act violently. Also, fear could be a motive. If she felt threatened in some way, she might resort to killing. In some cases, a sense of self - righteousness, believing she is doing the right thing by getting rid of someone she deems 'bad', could also be a motive.
One possible motive could be jealousy. If one friend is more successful or popular than the other, it might lead to envy and ultimately murder.
Financial gain could also be a motive. For instance, if there was an inheritance or some sort of valuable asset at stake, and someone wanted to eliminate the competition, they could use the 'killer soup'. Another motive might be jealousy. Maybe someone was jealous of another person's relationship or success, and decided to use the soup as a way to harm them.
One possible motive could be a desire for control. Serial killers often feel powerless in some aspects of their lives, and killing gives them a sense of power over others.
It's purely fictional. Usually, such names for stories or movies are made up to attract the audience with a thrilling and imaginative plot rather than being based on real events.
Self - interest is another motive. Like Susan Smith, who was having an affair and saw her children as an obstacle to her new relationship. She was so focused on her own desires that she committed the unthinkable act of killing her own children for her own self - serving reasons.
