Instead of assuming that the KJV is wrong, you also would be much better served by merely looking up the word “evil” in any good English dictionary or like I said earlier, the Bible itself to learn more about his own native language. I have often found that simply learning a bit more about our own language goes a long way in clearing up many an alleged “error” in the King James Bible.
The various meanings of the word EVIL.
The American Heritage Dictionary of the English language defines evil in this way.

The KJV itself has variously translated the underlying Hebrew word as “evil, wickedness, affliction, mischief, troubles, harm, adversity, sorrow, bad, ill and distress."
The NASB has translated this same word as “evil (136 times), bad, deadly, great, harm, miserable, misfortune, sore, trouble, ugly, wild, disaster and wretched”.
Likewise the NIV translates it as: “evil (190 times), wicked (24 times) bad, wrong, trouble, disaster, malice, wild, ugly, deadly, painful, ruin, ferocious, grievous, terrible, harm, great, sorrows, severe, unjust, vile, worse and wretched.”
You should take note of the significant fact that none of these Bible versions translates this Hebrew word as SIN.
God does in fact create and bring EVIL upon this world, either for punishment, judgment or correction.
In the book of Job we read: “What? shall we receive good at the hand of God, and shall we not receive EVIL? (Job 2:10).
