Your question deviates from the theme. It has been asked and answered in various ways throughout the ages. Nevertheless, since you ask my view: I suppose that the capacity to commit evil acts is the unavoidable consequence of creating a universe in which free moral beings have evolved. Since God chose to create such a universe, God is "responsible" for evil. God's alternative would have been not to create a universe, or to create a universe in which free moral beings do not evolve. In such a universe there would be no evil. The Christian view is that in the universe that God has chosen to create, evil does not triumph.
