You might find this interesting:"Deliberate self-harm in young adults may be associated with an increased risk of aggression toward others. A national registry study identified a cohort of individuals aged 15 to 32 years (n >1,850,000), which included patients who were treated for deliberate self-harm (n >50,000), and examined the association between nonfatal self-harm and subsequent conviction for a violent crime [97]. The mean follow-up period was eight years; violent crimes included homicide, assault, robbery, and threats. After controlling for potential confounding factors (age, psychiatric disorder, and socioeconomic status), the analyses found that conviction of a violent crime occurred twice as often in patients treated for self-harm, compared with the general population (hazard ratio 2.2, 95% CI 2.1-2.2). In addition, the rate among males and females with self-harm was similar (hazard ratio approximately 2)."
I have read that, if one is present, the risk of the other is greater. However, you can certainly have one without the other. Often these people are going to be very distressed. That distress can play out in a lot of different ways which may be unpredictable.
According to Freud, they both have the same psychological basis. Freud on Murder, Mourning, and Melancholia said homicide is violence toward others, while suicide is violence against itself. Palmer also shared this point of view of Freud. He said Suicide is inward aggression and homicide is outward aggression.
Before 1600, suicide was called self-homicide.
