Which social group had the most people executed during the Reign of Terror? Why is that surprising?

According to some estimates, the Jacobins killed about 100,000 people.

Explanation:

The Jacobin dictatorship or Jacobin terror is a period in French history that occurred during the French Revolution. Most people were killed because of accusations that they were supporters of the king and Catholicism. The Jacobin dictatorship eventually weakened due to popular opposition because the Jacobins liquidated many people. The liquidation of these people is not a big surprise because the Jacobins fought against royalist ideas.
