Is "the love of money the root of all evil" or is the bible wrong?

Starting with the King James Version at 1 Timothy 6:10:

“For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows.”

The word “all” is absolute, suggesting that every single evil act is monetarily motivated. But clearly, many evils in the world are not motivated by a love of money. For example, the 9/11 bombings. Bar fights over women where one participant dies. Roadside bombings that kill soldiers in Afghanistan.

The New International Version says it differently: “For the love of money is a root of all kinds of evil.” Which still technically means that there is at least one root or connection to “the love of money” in every evil committed.

It seems many bible scholars over time noticed this error and other translations of the scriptures were made where ”the root of all evil” has been changed to ”a root of all kinds of evil.” In these translations, the relationship between the love of money and evil is lessened from an absolute requirement to a mere potential ingredient.

So, which of these bible translations is wrong and which one is actually God-approved or Truthful? Also.. how will you decide?
