Pretty realistic depiction of many criminals’ life.
The guy sells chemical weapons and mercenaries to an upsart warlord in some remote desert / jungle / swamp / volcano lair, who creates unregistered pharmaceuticals and straight-out drugs as well as weapons, murders people and sacrifices their body parts to a make-believe god and kills, maims and enslaves people on a daily basis.
People who deal with such scum tend to be risk-takers that consume too much drugs and alcohol and often get into trouble.
