Power could be a motive. The villain might want to control everything in the novel's world, whether it's a kingdom, a powerful organization, or just a group of people. They see power as the ultimate goal and will do anything to get it, like eliminating rivals or manipulating others.
Another possible motive is envy. The villain could be envious of the hero's popularity, status, or special abilities. This envy drives them to try and bring the hero down, either by directly attacking the hero or by trying to undermine their achievements in the eyes of others.
One way could be to gradually show the villain's backstory that led them to be this way. For example, if they were wronged in the past, revealing this can make readers sympathize. Then, start having the villain do small acts of kindness secretly. This can start to shift the readers' perception of the character from pure evil to a more complex figure with potential for good.
Mental health issues also play a role. If the boyfriend has an undiagnosed or untreated mental disorder such as borderline personality disorder or schizophrenia, it can lead to unpredictable and violent behavior. Also, in some cases, financial problems in the relationship, like if the partner is seen as a burden or a threat to the boyfriend's financial stability, can be a motive for murder.
Motives in a 'Murder at My Door True Story' can be complex. It could be a combination of things. For instance, a person might be in financial trouble (like being in debt) and see the victim as an easy target for robbery. But during the act, things could get out of hand and lead to murder. Also, it's possible that the killer was part of a criminal gang and was following orders, which could be related to territory disputes or other gang - related issues.
Give your villain a unique appearance. Maybe they have a strange scar or an otherworldly glow to their eyes. Their fashion sense can also be distinct, like wearing all black with spiky accessories.
It could be that the pet's transformation into a villain forces the other characters to confront their own fears and biases. Maybe it brings out hidden strengths in the protagonist or causes rifts among the supporting cast. It all depends on the author's imagination and how they choose to develop the story.
The sense of isolation could be a motive. If Naruto never truly felt accepted in Konoha despite his efforts, he might snap. He's always wanted to be recognized, but if that never fully happens, he could turn on the village. For example, if he's constantly passed over for important missions or not given the respect he thinks he deserves as a powerful ninja.
In the 'My Husband Wants Me Dead Novel', it could be that he has some sort of mental instability. His perception of their relationship might be distorted, and he believes that her death would solve all his problems. It could also be due to a long - standing grudge or resentment that has built up over time in their relationship, and it has reached a point where he wants her dead.
Again, without knowing the specific story, it's difficult to say. But common motives in cases like this could be jealousy, anger issues, or control problems in the relationship.
The teacher might have had a deluded idea of 'helping' the student in a very wrong way. They could have thought that by abducting the student, they could 'protect' the student from something they perceived as harmful, like a bad home environment. However, this is still completely unacceptable behavior. Another aspect could be that the teacher was simply a criminal minded person who saw an opportunity and took advantage of the trust the student had in them.
