Question:
Why does God put murderers, rapists, and other awful people on the earth if He knows that they will just hurt us and won’t be saved anyway?
Answer:
God did not put people like that on the earth: they were babies when they entered their earthly existence. We were all born with a sinful nature, and we learned either to have respect for God and our fellow man, or we learned to despise and hate both as we matured. These characteristics are merely some of the things that we can become if we leave God and our fellow man out of our thoughts and considerations.
