There have been some people in the world's human history who have done terrible, despicable and unforgivable things.

These people are believed to have lost their humanity, their compassion and all sense of reason.

But, with all the terrible acts of violence and humiliation, the following people did one good thing in their lives, Telegraph reports.

Of course, this absolutely does not make up for their heinous actions, but it really does make you wonder how they became so evil.

Ted Bundy

One of the world's most notorious serial killers actually "saved lives before taking them".

In 1971, before becoming a crazed killer, Ted Bundy worked at a suicide prevention hotline.

He responded to the cries of distressed people and tried to persuade them to continue living instead of killing themselves.

His co-worker on the hotline, Ann Rule, wrote a book about her experience working alongside the "future killer".

But how he went from saving lives to taking them can perhaps be determined by psychologists.

Al Capone

Known as one of the most feared figures in organized crime, Al Capone led the Chicago cartel and proved to be the crime boss of all crime bosses by using brutal tactics.

But alongside his robberies, blackmail and violence, Capone is said to have also set up one of the world's first kitchens, the Telegraph reports.

In 1931, Capone opened a kitchen with a banner reading "Free Coffee Soup and Donuts for the Unemployed."

It is estimated that his kitchen has served 120,000 meals to Chicago's poor and homeless population.

Saddam Hussein

Saddam Hussein's long and brutal rule in Iraq led to expensive and unsuccessful wars with neighboring countries.

However, during his dictatorship, he did something that benefited the population.

Hussein was aware that knowledge is power, and he used this information to provide something good for his country.

He "installed" free compulsory education in Iraq in order to educate the entire population.

Napoleon Bonaparte

Napoleon Bonaparte wanted to conquer all of Europe and he went very far in his attempt.

Having kept Europe at war for 15 years, he proclaimed himself Emperor, drastically curtailed women's rights and abolished freedom of the press.

But in addition to these, he also introduced the Napoleonic code.

Under this code, he governed his newly conquered territories with strict laws that were established on the basis of equality rather than title.

This meant that men were all born with equal status and those who wanted a successful life could have one even if their family background was not from the upper class.
