Chilean here.
Pinochet was pretty bad, the only points he has on him was liberalizing the market, but even that was half-assed. Pinochet was never any sort of liberal, he admired various times admiring Stalin. Local around here "liberals" are more like Chicago School Neoliberals than, there are VERY few that have a more Austrian alignment. Pinochet had a more rural catholic conservative alignment, closer to Franco than American conservatives (American conservatives are VERY different to Catholic European and Latin American conservatives).
The AFP system inaugurated by the Chicago Boys was brilliant in paper, but poorly executed in the begging, and after two decades of left rule it's a nothing rotting corrupted corpse. A giant government and big corp sponsored Ponzi scheme.
In his rule almost every intellectual was questioned and watched, communist, liberal, anything. Torture, illegal detentions were carried with total impunity, with more than a million people needing to seek asylum abroad, more that 30.000 illegally detained and 3000 killed and missing.
Under his rule gun laws were toughened. Back in the day you could own and carry any kind of gun except automatics with a permit of the local police, ammo was taxed in a way similar to tobacco. Now firearms are extremely regulated by the Army, registration and licensing is centralized, and people can't own centerfire semi-automatic rifles, carry permits are only issued to biz fat cats and politicians, purchase of ammo is limited to 3000 rounds a year for sportsmen and hunters. All with the nice exception of "exemplar sportsmen" that curiously are only include businessmen and politics who get town own even automatic weapons. Under Piñera's neolib things changed for worse, under the Concertacion's left rule rule gun laws was a applied flexibly and it mostly boiled down to the judgement of local law enforcement, but Piñera's Hinzpeter started a crack down on "illegal and war weapons" that almost got scary shotguns like the Saiga 12 banned by name, and pellet guns needing a license and registration like firearms.
tl;dr he was just as bad as any dictator for the exception of a few points on economic policy
