Paul had blood on his hands,but never killed anyone,and he never admitted it .. he was the leader of the persecutions. He had Roman soldiers with him to either arrest, or kill them..the soldiers were with him when Jesus knocked him from his horse and blinded him,because they heard the voice,but saw no one. those that were arrested was later killed by the Roman Government.He was under the authority of the Roman Government to hunt down the Christians. If anybody hated Christians, it was the Roman Government, and those that sided with them.
