There have been studies showing a positive correlation between temperature and violent crime. [1] It's possible this behavior is just a manifestation of living in a warmer country.

Perhaps if you swapped the populations of Bogotá and Berlin you would find the new Berliners becoming more "chill" and the new Bogotans becoming more "hot-blooded."

Highly unlikely.

“Bogotá has an oceanic climate (Köppen Cfb) bordering on a warm-summer Mediterranean climate (Csb). The average temperature is 14.5 °C (58 °F), varying from 6 to 19 °C (43 to 66 °F) on sunny days to 10 to 18 °C (50 to 64 °F) on rainy days. Dry and rainy seasons alternate throughout the year. The driest months are December, January, July and August. The warmest month is March, bringing a maximum of 19.7 °C (67.5 °F).”

Berlin is literally a furnace compared to this, with average daily maximums well above 30 °C in the summer.

Looking at the chart Bogotá has an annual daily mean of 14.4°C, and is fairly consistent throughout the year. Berlin's is 9.9°C with hotter summers and colder winters. To make a definitive statement we would have to know whether spikes of hot temperatures or consistent warmer temperatures are worse for violence.
