Determining the "highest killing rate" is a complex issue, as it depends on how "killing rate" is defined. This can refer to:
- Homicide rate: This measures the number of intentional killings per 100,000 people in a given population.
- Overall death rate: This encompasses all deaths, including natural causes, accidents, and suicides, per 100,000 people.
- Execution rate: This measures the number of executions per 100,000 people in a given population.
Without further context, it's impossible to definitively answer which country has the "highest killing rate."
To get a more accurate answer, you need to specify which type of killing rate you are interested in.
For example, if you are interested in the homicide rate, you can find data on this from sources like the United Nations Office on Drugs and Crime.
