Answer:
god allows evil to exist because without evil we as a human race cannot grow and evolve from such evils done not only to our mankind but to our souls as well. In life you will come face to face with evil you should never cower in fear because god will always be by your side. For example in Psalms 23:4 "Even though I walk through the valley of the shadow of death, I will fear no evil, for you are with me; your rod and your staff, they comfort me"
