@Elmithian bro I do appreciate the attempt to teach me that the world is cruel, but that's not what I'm criticizing here. I am sorry you're mother was so vile and I promise you I'm fairly familiar with the way parents can hammer your brain into a shape until you don't which way is up.
I edit as a hobby (and rl). I edit stuff involving abuse. I edit edgy stuff. I have had conversations with writers like yourself, conversations that went along the lines of:
Me: I like this part where the mother suddenly attacks her son for simply not hiding his anger enough and despite that, the son rationalizes she was right to do so. But having her break a bottle and dig the shards into his cheek reads a little cartoonish.
Writer: well originally I based this off my mother and what she actually did was dig her fingernails into the skin under my eyes to rip at it, but I thought readers would think that was unrealistic. Should I change it back?
Me: ...Yeah. That...that would fit the tone better. More, uh, visceral.
I'm
not criticizing this story for having a tragic backstory, abusive parents, children who are fucked up due to fucked up parents, etc. That is why I specifically said
It's not bad to make your antagonist sympathetic. It's not bad to have characters who seem cruel until you're given their perspective. It's not even bad to have a character happily accept a bully doing a 180 because they're suddenly receiving gifts and positive attention. All of those things are good.
I'm annoyed by this story because the writer isn't doing the legwork. I'm not incredulous that someone would have a dead mom, a new alcoholic mom, a wimp dad, two kids she's expected to be mom to, AND be bullied - I'm irritated that that
all of this info was dumped in a single chapter. It's just boom, boom, boom, boom, are you sad yet?
Let me reiterate - I can see what the writer is TRYING to do. A subplot where the "evil" character is shown to be simply trying to survive in a hellish world, that the "trying to survive at all costs" mindset does not create kind people? That abuse leads to fucked up mentalities? That you can grow callous to the screams of a child with enough prodding? That can be great. But this story doesn't have the skill and it's clunky as hell. They're not giving characters enough room to breathe, the pacing is all over the place, and the backstories deserve a lot more foreshadowing than they're receiving.
