The correct answer is He was sad about the execution but satisfied with the result. Cromwell was an English military and political leader, who entered the English Civil Wars (1642–1651) on the side of the Roundheads or Parliamentarians and, due to his commanding capacities, became one of the main commanders of the New Model Army, which played a very important part in defeating King Charles I and his supporters (Cavaliers/Royalists). Cromwell was the one who pushed towards the execution of King Charles I because he believed that there would be no settlement in England while the king lived. Therefore, this cruel act of violence (the King’s execution) was necessary to free England from the rule of a tyrant, who had been condemned as a traitor to his own nation; this is why it can be said that, though Cromwell was not happy with the execution, he was satisfied with the result.
