So we are in fact extrapolating from 4 conversations that OP was emotionally abusive, therefore he was physically abusive, therefore he intentionally killed Reeva? Did I get it right that time?
No, not exactly. There is adequate proof in his texts that he was definitely emotionally abusive. Physical abuse is something that happens in a high percentage of emotion abuse cases.
I know a number of posters want to write off his texts as nothing more than a tiff but we have had at least three, and possibly 4, conversations that show this man was a control freak and verbally and emotionally abusive.
I think if one has worked with or lived with emotionally abusive patients/family these texts immediately shout TROUBLE AHEAD. The abusers can be perfectly normal much of the time, and loving, and are always sorry about the abuse (usually through fear of loss of their partner). Often their behaviour is not apparent to others outside the family.
In my father's case it was because he couldn't bear the thought that my mother had friends for whom she felt any affection. These were female friends. He also caused her estrangement from her brothers and sisters with various verbal threats and non personal violence. He just couldn't deal with the fact that there were other people in her life, even her brothers and sisters for whom inevitably she had affection.
He was even jealous of us, his children. If we were to visit them for lunch he would throw a fit because one or other of us would go to the kitchen to help/talk to our mother. However, he never threatened any of the girls (strange that) but he did break canes over the boys when they were younger. So there was physical violence perpetrated on others at times.
I agree that it does not mean that being emotionally abusive/unstable always leads to murder but there is plenty of evidence that in a large percentage of cases it escalates into violence. In OP's case, I think he has demonstrated that he does get "out of control" if irritated which IMO opinion suggests he would have, at some stage, caused injury.
I would be very interested to learn the reasons for his parent's divorce. His father is a gun freak, perhaps he also had the rather short fuse that OP displays at times. No doubt this information is available somewhere.
