Born to unknown parents, he lived his youth in Lodi, and joined the Fascist movement at age fifteen, becoming a squadrista in the "action squad" led by Luigi Freddi.

He then returned to Florence on 17 September 1943, where he joined the Italian Social Republic and founded a special police unit, the Reparto Servizi Speciali (Special Services Unit), devoted to repression of anti-Fascist activities, which would become best known as "Banda Carità" ("Carità gang"); its members initially numbered about sixty, divided into three groups, and soon became infamous for their widespread use of torture (such as beatings, electrical shocks and tearing of nails) on suspected Resistance members.

Addressing these accusations, Carità personally wrote to Mussolini on 14 December 1943, claiming that his actions had been exaggerated and that he was merely reviving the early traditions of squadrismo, the only methods that would be effective in crushing the enemies of the regime.

Other members of the CLN were arrested, and the linotype of the partisan newspaper La Libertà was captured; for these successes, in late February 1944 Carità was promoted to seniore (Major).

On 26 April 1944 his men captured another Communist Resistance leader, Bruno Fanciullacci, who was tortured without revealing anything and was later freed by a coup de main enacted by his comrades of the Gruppi di Azione Patriottica.

[8][11][7][14] On 8 July 1944, as the Allies advanced towards Florence, Carità left the city and moved to Bergantino and later to Padua, where he continued his anti-partisan activities, infiltrating members of his unit in the ranks of the Resistance and arresting and torturing political opposers.
