No.

The US has way more guns and gun owners than ever before and we didn't have an increase in violence or murder across the board.

The facts and statistics don't agree with your theory.

In fact, the murder rate in the US is only as high as it is due to a select bad cities.
There's plenty of States in the US with very little gun control laws that have very low crime and murder rates.

Other factors contribute to violence. If guns caused people to kill than we would see millions upon millions of murders per year. We don't.
