Oh, I have no doubt that heretics were sometimes put to death. Heresy was considered a grave offense and it's spread would jeopardize the souls of people.
So, I suppose your Baptist church is 'the true church'? Do you also, as so many on the board do, believe in Baptist Successionism?
Baptist Successionism can never be disproved because all that is required for their succession to be transmitted was a small group of faithful people somewhere at some time who kept the flame of the true faith alive. The authors of this "history" skim happily over the heretical beliefs of their supposed forefathers in the faith. It is sufficient that all these groups were opposed to, and persecuted by, the Catholics."
Thankfully intellectually honest Baptists, such as James McGoldrick who was once himself a believer in Baptist successionism are conceding that this "trail of blood" view is, frankly, bogus. McGoldrick writes:

What about Cardinal Hosius and his 4th century Anabaptists?
No, not a succession but rather a promise of perpetuity--Jesus told His disciples He would never leave them or forsake them. Also: "Lo, I am with you always, even to the end of the age." He has kept His promise. God has had a remnant in every
generation--what they may have been called is not relevant.
Even so, come, Lord Jesus.
Bro. James
Extensive graduate study and independent investigation of church history has, however, convinced [the author] that the view he once held so dear has not been, and cannot be, verified. On the contrary, surviving primary documents render the successionist view untenable. . . . Although free church groups in ancient and medieval times sometimes promoted doctrines and practices agreeable to modern Baptists, when judged by standards now acknowledged as baptistic, not one of them merits recognition as a Baptist church. Baptists arose in the 17th century in Holland and England. They are Protestants, heirs of the reformers. (Baptist Successionism: A Crucial Question in Baptist History [1994], 1–2)
