Oh yah the brutality continued unabated until he stepped down. However, the body count was highest in 1973 and tapered off as their were fewer dissents in the country (fled abroad, gone underground, eliminated)![]()
Which is how it tends to work. Much of the violence of Franco's White Terror and impieza policy took place during the initial years of his dictatorship following the end of the Spanish Civil War and during the war itself.
Back on the main topic if, as DValdron suggests, you end up with a rotating series of coalitions similar to Italy it wouldn't be surprising if there was also a rise in low-level political violence from all ends of the spectrum. There's going to be at least some of the more radical Communists who will see Chile as ripe for some sort of violent revolution and, as earlier assassinations show, elements within the military and those who backed the coup OTL who will feel similarly. It probably won't reach late Weimar levels of street fighting but it would probably be something like what was seen in Italy during the 70s and 80s or West Germany with the Red Army Faction and Bader-Meinhoff but from all sides involved.
