At three I had a feeling of ambivalence towards my brothers, And so it follows naturally I've poisoned all my lovers, But I am happy now I've learned the lesson this has taught, That everything I do that's wrong is someone else's fault!
A particularly Anvilicious case is Harry Chapin's "Sniper," about a boy whose mother never makes time for him, so he grows up to be a deranged mass murderer who explicitly voices his hatred for her at the climax. Can be considered a darker version of Chapin's "Cats in the Cradle."
The person the singer is singing to in "Numb" by Linkin Park has one, apparently ("but I know you were just like me with someone disappointed in you").
Same in "Points of Authority":
You want someone to hurt like you (you live what you've learned)
You want to share what you've been through (you live what you've learned)
The Sara Bareilles song "Machine Gun," about the jerk whose sole purpose in life is to aggravate those around him:
Maybe nobody loved you when you were young Maybe boy when you cried nobody'd ever come Will you try it once? Give up the machine gun...
The Wound that Never Heals by Jim White, is about a Black Widow. It has this to say about her backstory:
She runs from devils, she runs from angels
She runs from the ghost of her father and five different uncles.
Blinded by their memory, seared by their pain
She'd like to kill 'em all, yeah, kill 'em all again
She don't think much about what she's done, or the funny way she feels (No she don't)
To her it's just a condition she picked up as a child
A little thing she calls "The Wound that Never Heals".
I think someone was mean to you, when you were little
That's what I think
I think someone was mean to you
Had Enough by Breaking Benjamin may be an example of this trope, as it could be about an Omnicidal Maniac who is motivated by hatred for someone, possibly his father.
You should have learned by now, I'll burn this whole world down
I need some peace of mind, no fear of what's behind
You think you've won this fight, you've only lost your mind
You had to have it all, well have you had enough?
You greedy little bastard, you will get what you deserve
When all is said and done, I will be the one
To leave you in your misery and hate what you've become
Tomahawk's self-titled album is supposedly a concept album about a Serial Killer, which would make the song "Flashback" the main character's Freudian Excuse, as it's about his repressed memories of a disturbingly abusive childhood.
