Whatever this person is trying to prove, they are right that Paul murdered God's children before his conversion:
Act 8:1 And Saul was consenting unto his death. And at that time there was a great persecution against the church which was at Jerusalem; and they were all scattered abroad throughout the regions of Judaea and Samaria, except the apostles.
Act 8:2 And devout men carried Stephen to his burial, and made great lamentation over him.
Act 8:3 As for Saul, he made havock of the church, entering into every house, and haling men and women committed them to prison.
Act 9:1 And Saul, yet breathing out threatenings and slaughter against the disciples of the Lord, went unto the high priest,
Act 9:2 And desired of him letters to Damascus to the synagogues, that if he found any of this way, whether they were men or women, he might bring them bound unto Jerusalem.
1Ti 1:12 And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry;
1Ti 1:13 Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did it ignorantly in unbelief.
1Ti 1:14 And the grace of our Lord was exceeding abundant with faith and love which is in Christ Jesus.
1Ti 1:15 This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.
Paul never let himself forget that he had once been Saul.
I think we ought to take a lesson from him here...let us not forget our own sins, that we might avoid committing them again...
