You picked out the weakest argument and completely ignored the critical ones on either side of it. That tells me you're not really interested in understanding why their lives were taken when other followers of Jesus Christ, with even more egregious sins, were apparently left alone.
You didn't even "get" the weakest argument since, among other reasons, you're still under the delusion that Jesus came to save everyone when there is abundant Scripture that clearly says otherwise.
In addition, you don't understand the difference in Saul's spiritual condition and legal standing before God subsequent to his conversion.
