A strong believer in the connection between democracy and nonviolence, he fought in favour of some radical civil and political reforms to improve civil rights in Italy. One of his main conquest was the right to divorce and abortion. Abroad, he engaged with the defence of civil rights in the Eastern European countries, and was therefore arrested in Sophia in 1968. But the passion towards human rights made him pursue one of his many hunger strike to pursue a moratorium on death penalty, improvement of the unbarable conditions of prisoners within the Italian jails.
