9. Rafael Trujillo
No notorious dictators come without their trustworthy inner circles of advisers, and Rafael Trujillo chose his wisely. On second thought, maybe he didn’t; he appointed his 3-year-old son as colonel.
Trujillo took over the Dominican Republic after being trained by the US Marines. He orchestrated thousands of killings of civilians, a lot of whom were Haitians. He considered his slaughtering a “remedy” to his unquenchable thirst for blood, apparently.
Many of his killings were determined by the victims ability to pronounce certain words with a trill, or in other words, a rolling “r” to determine if they were “real Dominicans.” What a sadist.
