In 'becoming the villians family novel', power and corruption could be important themes. The villain's family might be involved in power - seeking and corrupt practices, and the main character has to navigate through this. Also, identity is likely a theme as the character is changing their own identity by becoming part of this new family.
I'm not sure exactly as I haven't read the novel. But there's probably a protagonist who is the one becoming part of the villain's family. Then there would be the members of the villain's family, like a powerful and maybe cruel father figure in the family who is the main villain.
One main theme could be redemption. The protagonist might be trying to change the fate of the villain's family, which implies a form of redemption for the family's actions. Another theme could be family dynamics. Despite being the 'villain's family', there are likely complex relationships within the family that the story explores.
Well, in 'villians are destined to die novel', a main theme is probably moral complexity. Villains are not just one - dimensional bad guys. Their actions might be influenced by their past experiences or the circumstances they are in. And then there's the theme of mortality. Their 'destined to die' part shows that no matter how powerful or evil they seem, death is an inescapable end for them. Also, power dynamics could be a theme as they use their villainous powers and face consequences.
Well, love might be a theme too. It could be a love that defies the expectations of the 'villain' label. Maybe the protagonist falls in love with someone in the villain's family and this love challenges the pre - conceived notions about the family. Also, power struggles within the family could be a theme. With the villain's family, there are likely to be fights for power, inheritance, or control.
I'm not sure specifically as I haven't read the exact novel. But usually, in such novels, the main villains could be power - hungry individuals. They might be those who have been wronged in the past and now seek revenge in a very extreme way, making them villains in the eyes of others.
I think 'Overlord' is a great one. The protagonist, Momonga, is an undead overlord in a new world, and his actions and the way he rules his territory can be seen as villainous in the eyes of some. 'Akame ga Kill!' also has some interesting villain - like characters. The organization in the anime, such as Esdeath, has cruel and power - hungry motives. Another good one is 'Kabaneri of the Iron Fortress'. The Kabane are like villains, and the story also shows how some humans can turn into something close to villains in the face of survival.
Another possible theme is loyalty within the family. Family members may have to decide where their loyalties lie, whether it's with the family as a whole or with their own individual beliefs. This could lead to internal conflicts and drama within the family unit.
As I don't know the specific 'Naumann family novel', it could have themes like family loyalty. Family members usually support each other through thick and thin in family - focused novels.
Power and politics could be one main theme. In many royal family novels, the struggle for power within the royal court is often depicted, showing how different characters vie for the throne or influence over the king or queen.
One of the themes could be family loyalty and betrayal. In a powerful family like the Borgias, members might have to choose between loyalty to their family and their own self - interests, which could lead to betrayal. This dynamic can create a lot of drama and tension in the story.
