Many dictators / leaders have committed a lot of crimes, genocides and so on. Yet I haven't heard "average Americans" having same kind of opinions about Pol Pot, Ceausescu, Hutus in Rwanda and others like they have about Hussein.
Back in the 80s when Iraq used chemical weapons against Kurds, the US was actually helping them. (

A UN security council statement condemning Iraq's use of chemical weapons in the war was issued in 1986, but the US and other western governments continued supporting Baghdad militarily and politically into the closing stages of the war.
When Iraq invaded Kuwait, it was the United Nations who ordered Iraq to withdraw, not the USA.

After an attack to US on 11th Sep 2001, an attack that was planned by Osama Bin Laden and carried out by al-Qaeda (
story), US declared "war on terror" and, for some reason, considered Iraq to be a threat too. (

Waging a war on terror is a complex business. In fact many in Britain are convinced that the regime of Saddam Hussein, brutal as it was, had little to do with terrorism per se.
Terror, n.
1. Intense, overpowering fear. See Synonyms at fear.
2. One that instills intense fear: a rabid dog that became the terror of the neighborhood.
3. The ability to instill intense fear: the terror of jackboots pounding down the street.
4. Violence committed or threatened by a group to intimidate or coerce a population, as for military or political purposes.
5. Informal. An annoying or intolerable pest: that little terror of a child.

War against that is, in my opinion, impossible to win.
In November 2002, after weeks of wrangling, the UN Security Council passed resolution 1441. It was designed to force Iraq to give up all weapons of mass destruction and threatening "serious consequences" if it did not comply. Iraq accepted the terms of the resolution and weapons inspections resumed.
In early February 2003, US Secretary of State Colin Powell told the UN that inspections were not achieving the disarmament of Iraq. The US and UK pressed for a new resolution authorising military action against Iraq. France and Russia opposed this resolution, and threatened to veto it.
The resolution never came to a vote and early on 20 March, the US-led campaign to topple Iraqi Saddam Hussein began.

It's been over a year since resolution 1441 was passed and no WMDs have been found.
Conclusion: I can only think of one thing
An average American would have against Hussein - having their loved ones killed in a war against Iraq, but that's because they were ordered to go there.
Personally I'm glad that there's one brutal dictator less in this planet (granted, he's still alive, but not ruling).
