Inventions that were worst for the world, for the most part, are all things created with good intentions that have changed the world for eternity. While few inventions are perfect, these stand out as among the best that created the worst outcomes. These are not just products nobody needs these are inventions that made the world a worse place to live.

Few can deny that the invention of automobiles and airplanes made traveling much more efficient but it's hard to forget that cars pollute the earth and airplanes can be used for terrorism or war. The same goes for rockets. They launched people into space but also carried nuclear weapons that caused mass destruction. Television and the Internet changed how we interact and share information, but sitting in front of a computer monitor or TV for countless hours, along with corn syrup, isn't helping fight obesity. Nuclear fission creates power but can also wipe entire populations off the globe when used for evil.

Then there are other inventions where it's hard to find a benefit. Cigarettes are a proven cause of death in roughly half who smoke. How many other products that are so widely used can say the same? Along the same lines, there is very little good to say about gas chambers whose sole purpose is to kill humans and animals.

Unlike the most useless inventions which aren't so much harmful as they are just plain dumb, these inventions changed the course of history forever and are thought of by many as the worst inventions of all time. Think of a world with no gun deaths had gun powder never been invented or a history with no slavery or Civil War had the cotton gin never been created. That's not a bad reality to consider.

Ever hear those commercials about one product that kills roughly half of it's users? Yep, those are for cigarettes. Originally developed back in the ninth century for religious rituals, today cigarettes are highly addictive, contain a whole slew of chemicals and post serious risks to those who smoke and anyone around them.

Gas Chamber

Unlike some of the other inventions on this list which were created with good intentions, the gas chamber has few, if any redeeming qualities. Yes, someone decided that there should be a large chamber where people and animals can be placed, then sealed off and injected with poisonous gas.

Yes, this killed millions and was the preferred method of death during the Holocaust. There is no benefit for having the gas chamber and is one of dozens of inventions that just add no good to this world.

Agent Orange

Way back in 1943, plant biologist Arthur Galston was studying a way to alter the growing season of soybeans when he started to work with triiodobenzoic acid as a plant growth hormone. It didn't work too well in excess, defoliating most of his crop and raising concerns about safety.

Not soon afterwards, the US Army, working with the University of Chicago, learned that this compound could destroy the crops of enemies and went on to be used in the Vietnam War, among other places. The side effects however killed an estimated 400,000 people.

Leaded Petrol

Scientifically known as Tetraethyl lead or TEL, this compound initially was seen as an amazing new invention and was added to gasoline starting in the 1920s. It was cheap and boosted the octane and engine compression in vehicles. It was however extremely toxic, polluting land, leading to lead poisoning in countless individuals and even linked to an increase in violent crime as the neurotoxins caused harmful side effects to the brain.

Also, the CFCs, or chlorofluorocarbons as they are professionally known, produced by lead petrol continue to threaten the earth's ozone layer to this day.
