I don't know who the main characters are since I haven't read the novel. But generally, in a novel with such a strong title, the main characters are likely to be those in a relationship where one has these extreme feelings towards the other.
Perhaps the main theme is about the dark side of human emotions. In the novel 'There were times I wished you were dead', it may show that even in normal - looking relationships, there can be hidden depths of animosity. It could be exploring how these negative feelings can fester over time and what it means for the individuals involved. It might also be a commentary on how difficult it can be to overcome such extreme emotions and how they can shape a person's view of another.
I'm not sure specifically as I haven't read the novel. But usually in a novel with such a title, there would be a character who harbors the 'wished you were dead' feeling towards another character. So there would be at least two main characters in this kind of conflict - ridden plot.
The main theme could be about complex relationships. It might explore themes like hatred, revenge or the extreme emotions that lead a character to wish someone dead.
Since I don't have a lot of information about this novel, it's hard to say exactly who the main characters are. However, we can assume that there is likely a protagonist who harbors this dark thought about another character, perhaps an antagonist or someone who has wronged the protagonist in some way in the story.
Well, it could be centered around the idea of emotional turmoil. In many novels, when a character expresses such a strong negative sentiment, it often reflects on the overall state of the relationship in the story. Maybe it's about two characters who have had a long - standing feud or some sort of misunderstanding that has led to this extreme feeling.
The novel likely explores complex emotions and interpersonal relationships. Maybe it delves into the darker side of human nature and the consequences of such thoughts.
Often in a novel with such a title, there might be a protagonist who is deeply conflicted, perhaps a character who has been wronged in some way by another character. So the main characters could be a victim - like figure and the antagonist who has caused the pain. However, without reading the book, it's just speculation.
