You probably mean dictator, not king, which is a very different thing. A Roman dictator was a strong and capable leader who would TEMPORARILY assume great powers, set everything right that was wrong, and then relinquish power back to the people, i.e. return to a Republic.
As for why they might have wished this: for the same reason people in the United States wish it now. The Senate appeared infected with squabbling and petty intrigue, ineffectual, the great men all climbing over one another for power and paying no atention to the real needs of the people. There was widespread belief that in the past leaders had been more altruistic, simpler, of better moral character. And that what was really needed was some kind of strong, wise leader who would take great power temporarily and set everything right -- purge the Senate of its selfish silly tendencies, right the ship of state, put purity and morality back into public service, maket he trains run on time, et cetera.
Nothing has really changed since then. It's completely routine for republican and democratic forms of government to be perceived as so infected with partisan squabbling, immorality and corruption, and personal struggles that people quite willingly turn great power over to dictators in the (foolish, as it turns out) hope that this will fix things, and be temporary. History is stuffed with examples, from Caesar to Stalin, and there will be many more.
In fact, the Founders of the United States took great pains to attempt to design our form of government so that it would be unattractive to would-be Caesars, and not work well with them. This is one of the main reasons for the separation of powers and the strict limitations on what the Federal government could do. How long this trick will succeed is an interesting and as yet unresolved historical question.
