I appreciate your naivete but we have to face the truth. The homicide[+] rate of South Africa (as of 2018) is 36.40. For comparison, Afghanistan is 6.6. The US sits at 4.96. Most of Europe is below 3. And that's just the kiling part. South Africa is notorious for its rampant sexual violence. [++]
[+] Within the broad range of violent deaths, the core element of intentional homicide is the complete liability of the direct perpetrator, which thus excludes killings directly related to war or conflicts, self-inflicted death (suicide), killings due to legal interventions or justifiable killings (such as self-defence), and those deaths caused when the perpetrator was reckless or negligent but did not intend to take a human life (non-intentional homicide). https://en.wikipedia.org/wiki/List_of_countries_by_intention...
