Since we don't yet know what makes them dangerous, we don't know if a genetic modification could make them safe. Robert Plombin's "Blueprint" https://mitpress.mit.edu/9780262039161/blueprint/ suggests that most complex human behavior is influenced by thousands of single nuclear polymorphisms, and each dangerous individual would require a whole raft of individually tailored genetic modifications. > It could even be a pandemic virus.
