Why were gunpowder plotters treated so harshly?

The gunpowder plotters were treated harshly due to the severity of their conspiracy to assassinate King James I and blow up the House of Lords in 1605, an act aimed at ending Protestant rule in England. This plot was seen as a direct threat to the monarchy and the stability of the state, prompting a swift and severe response to deter similar insurrections. The harsh punishments, including torture and execution, were intended to serve as a warning to others and to reinforce the government's authority in a time of heightened tensions between Catholics and Protestants.
