Um, no. You must've got that off a silly TV show. Bruno wasn't executed for having a "different worldview", he was executed for heresy and blasphemy. His "worldview" was pretty irrelevant to his trial, in which he was charged with speaking against the Catholic Church and its priests, dealing in magic, the occult, and reading omens, preaching against the divinity of Christ, the Virgin Mary, transubstantiation, mass, and the Holy Trinity, and teaching reincarnation and that souls can inhabit beasts. He was burned at the stake, his soul cast into oblivion, and his remains dumped in a river.
It wasn't his internal beliefs that got him killed, it was his religious treason and trouble making. He was sold out and accused by a Venetian nobleman in a very liberal city teaming with Muslims, Jews, Protestants. He was sold out because he had promised to teach some memorization tricks to the nobleman and then tried to leave before he'd taught much of anything, so the nobleman was enraged and locked Bruno in the attic and threatened him with dire consequences if he didn't continue his lessons. Bruno refused, so the nobleman (from a long family of doges of Venice) penned an angry letter to the Inquisition, saying:
I, Zuane Mocenigo, report by obligation of my conscience and order of my confessor that I have heard Giordano Bruno of Nola say, while conversing in my home: that it is a great blasphemy for Catholics to say that break transmutes into flesh, that he is an enemy to the Mass, that no religion pleases him, that Christ is a wretch, and that if he did such wretched work as deluding the people, he could easily have predicted that he would be hanged, that God has no distinction of persons, as this would constitute an imperfection in God, that the world is eternal and that there are infinite worlds, because he says that he wants to do what he is able to do, that Christ performed apparent miracles and was a magician, and likewise the apostles, and he had a mind to do as much as they and more, that Christ showed reluctance to die, and fled death as long as he could, that there is no punishment of sins, and that the souls created by nature pass from one animal, and that just as brute animals are born by spontaneous generation, so are human beings when they are born again after a flood.
He revealed plans to make himself the head of a new sect under the name of a new philosophy. He said that the Virgin could not have given birth, that our Catholic faith is full of blasphemies against God, that friars should have neither the right to debate nor incomes, because they pollute the world and are all asses, that our opinions are the teaching of asses, that we have no proof that our faith finds merit with God, and that to lead a good life it is enough to do to others as we would have them do to us, and that he laughs at all the other sins, and he marvels that God can bear such heresies from Catholics. He says he wants to tend to the art of divination, and draw the whole world behind him, that Saint Thomas and all the doctors of the Church know nothing in comparison with him, and he would so enlighten all the best theologians in the world that they would have not a word to say to him.
The angry letter went for several pages. That got Bruno picked up by the Inquisition in Venice, where he recanted and begged forgiveness, which was granted. But then the Roman Inquisition requested his extradition. Normally Venice denied all such requests, and Rome's interest was in Bruno's German contacts, which could spell serious trouble in a period of revolution and religious war, and there's Bruno, apparently trying to start a new powerful revolutionary sect set against the Catholic faith, and a sect that must've seemed the work of Satan, at that.
Meanwhile, back in the modern world, the University named after Cardinal Bellarmine, who convicted Bruno of blasphemy and heresy, went on to win the 2011 NCAA men's division II basketball championship! That makes it pretty obvious which side God is on. One guy gets burned to death and dumped in a river. The other guy has his team cut down the nets.
