I also think I may need to kill one of my favorite boys from my current work to add to some character arcs and raise the stakes of the story, and let's just say I'm not very happy about it.
Yeah, I'm kinda in a similar situation. I've recently decided to kill off two of my characters . I've nearly cried while writing near death scenes (not because my writing is that good, but probably because I'm just really attached to my characters and was listening to a sad song) so I'm probably going to be a mess when I have to kill off these characters.
I don't really want to do it, but I feel like it lowers the stakes if the villains don't kill anyone. At least one of the characters gets killed off by a family member, so I feel like that kind of shows that the villains aren't messing around. Like, if they'll kill their own family members, then they'll kill just about anyone. Plus, one death will raise the stakes for one character, and the other will just create all kinds of internal conflict for another. I stand by my decision, but I'm not exactly looking forward to it.
