I no longer believe I had to kill people in other lifetimes

Why?

Recently I have realized that my soul is billions of years old so it is likely I never had to do that ever simply because if I was born I realized who I was young enough not to be put in that position. The older the soul the less likely one would be put in positions where harming others would be necessary?

Why?

Because if you are that old as a soul you would also know how to alter time and space with your mind not to be put in that position.
