I believe that Able being hit in the head by a rock explains a lot of his character.Β
A hit on the frontal lobe can cause:
(Attention) Changes in activation and orienting responses and decreased directed forms of attention.
(Social and emotional behavior) Lack of respect for social norms, emotional lability, sexual inadequacy, excessive familiarity, and inadequate emotional interpretation.
(Language) Aphasia, mutism, naming errors, and lack of verbal control over behavior.
(Memory) Amnesia, defects in working memory, and metamemory.
(Motor skills) Pathological reflexes, neglect, tone and gait abnormalities, changes in sphincter control, hyperactivity, utilization behavior, and perseverance.
(Perception) Limitations in eye movements and inadequate perceptual interpretation.
(Personality) Moria, impulsivity, pseudo-depression, and pseudo-psychopathy.
(Intellectual processes) Difficulties of abstraction, concept formation, and tendency to present infantile ways of thinking.
So, what's the big deal with this? The big deal with all of this is in real-life examples of serial killers who suffered from a head injury during their childhood and adolescence, examples are Ed Gein, Jerry Brudos, Gary Heidnik, Richard Ramirez, Henry Lee Lucas, and Alexander Pichushkin.
The symptoms listed above are from Dysexecutive syndrome, noted before to be caused from a head injury, specifically in the frontal lobe, the most notorious symptoms of Able correspond to social and emotional behavior, personality, and intellectual processes, which are noted in his article.
(I don't know if Dr.Clef has this in mind while doing the revision, but I like this explanation better than "he just has the mind of an edgy teenager" that is usually writen).
Summary: Abel probably has Dysexecutive syndrome and that Cain really fucked up big time.
So thanks for reading my little thoughts before bed.
