Wikipedia says: An ardent fascist, Hernández Martínez led a military government that actively suppressed opposition, most notably the Salvadoran peasant revolt of 1932 led by Farabundo Martí, where thousands of indigenous Salvadoran people were systematically murdered if they were suspected of collaboration with the communists. This massacre came to be known as La Matanza, and the specific number of victims is unknown but estimates range from 10,000 to 40,000. The 1939 Constitution expanded voting rights to women for the first time. He also censored the media, banned political opposition, abolished local elections, rigged national elections, and severely repressed dissidents.

Hernández Martínez was a believer in fringe occultism. When a smallpox epidemic broke out in San Salvador he had colored lights hung around the city, in the belief that this would cure the disease. He also believed in reincarnation and once said that "It is a greater crime to kill an ant than a man, for when a man dies he becomes reincarnated, while an ant dies forever."
I believe that there has been no justice for General Martinez.
Every article focus too much on the revolt repression and the way he handed the communists. There was more to him than stopping a revolt the classic way.
He cleaned up the fisco and reduced crime rate to near zero, which in that time was more horrible than the current situation. During his administration the country was self suficient and paid the whole external debt.
The leftist groups on the country took to heart satanizing him, for you may know this, salvadorean people are superstitious and not was it something he alone believed. It's been in our culture for ages, so it is that there's a rather LARGE amount of doctors that believe in curses up to this day.
I'm not saying this out of pasion or political reasons(I irrationally despise politics). It has always been my belief to "give respect to those who deserve respect" and "not judge a person only for either their good or wrong doings, but for them all".
