This can be occasional TruthInTelevision (with exceptions of course), with many cases in criminal psychology finding a link between anti-social behavior and a history of child abuse/neglect, but UsefulNotes/SigmundFreud was mostly RightForTheWrongReasons (he pinned this on hysteria and [[FreudWasRight sexual repression problems]]), and this can actually be explained by modern concepts such as Social Learning Theory. Children are actually more likely to do (and exaggerate) behaviors if other people did them, especially when behavior comes with appealing rewards, and even if said behavior is bad/violent and the very people who are doing it do try to convince them to [[{{Hypocrite}} never do said violent behavior]] (how actions speak louder than words is hence why children are susceptible to DoNotDoThisCoolThing). For example, if someone was abused by their parents, he will be more likely to learn how to abuse his own children.

In behavioral psychology/operant conditioning, the child's bad behavior can be amplified by [[NoGoodDeedGoesUnpunished receiving constant punishment, discouragement, bullying, manipulation and abuse for good, altruistic behavior]] (e.g., TurnTheOtherCheek in childhood only gets [[BreakTheCutie disproven]] as [[WideEyedIdealist wide-eyed idealism]]), and how the child observes [[KarmaHoudini bad people surviving and even getting rewards for arbitrary violence]] (like said abuse). Ergo, it becomes [[TheSocialDarwinist reasonable to dispose altruism and adopt ruthlessness for the sake of survival]], [[AmbitionIsEvil self-improvement]] and other such incentives. This conditioning is particularly devastating in childhood since children, without an inherent moral code, need outside reinforcement and role models to develop ethical behavior and [[NoSocialSkills Social Skills]]. In this case, a Freudian Excuse would have more impact if coupled with AdultsAreUseless which gives the child a jaded perception that [[CrapsackWorld the adult law is useless in general]].

In Psi-Theory, constant abuse in childhood can lead to a persistent feeling of incompetence. Strategies to resolve this feeling, among others, can be the accumulation of political power, or violence towards weaker persons. Sometimes, in more neurologically based cases, the "Freudian Excuse" can be caused by mere brain damage, neglected brain development or a persistent "fight-or-flight" response state which was the result of said abuse. Whatever the reasons, this trope is often brought up in Real Life discussions as a form of {{insanity defense}} and/or a reason to [[ThereShouldBeALaw ban corporal punishment]].
