Let's assume, just for laughs, that I know a little history.
Many people have been burnt alive, Bruno included, Galileo excluded.
Bruno was a singular immolation for multiple heresy's, the Cathari were immolated en masse along with non heretics (for God to sort out) .. but none for claiming the earth traveled about the sun, Bruno (IIRC) made waves for denying actual core beliefs.
( Wikipedia cites Bruno not accepting the Trinity, the divinity of Christ, the virginity of Mary, transubstantiation, et al as the main items on the docket .. more than enough for the church of the time )
Galileo wasn't burnt at the stake and many would hold that despite popular opinion his trial had less (almost nothing) to do with his support of heliocentrism nor even his "mocking" of an old friend and now Pope as "Simplicio" and was instead rooted in the worst kind of corporate infighting - he had savagely insulted people that ascended to power within the church who seized their chance for revenge when it came.
You can always find a hook to hang people upon if you look hard enough, the actual reasons for wanting them hung are often orthogonal to any claimed in performative public trials.
