Well, he seems to have been obsessed with Jesus, first in persecuting Christians, and then in believing that Jesus spoke to him. He reminds me of that character in Les Miserables who hunted Jean Valjean for decades. Obsessed, first with wresting believers away from Jesus, and then with basically taking over the wheel. This is a personality type one would avoid in real life.
You must not have much experience with those who convert and are transformed by the Grace of God. For example, take a look at prison ministries. I pinged a gentlemen who sponsors former drug addicts and criminals who had their lives changed by Jesus Christ. I have seen former alcoholics and drug addicts lead those under the same chains to free themselves of addiction. In the case of Paul of Tarsus his "intervention" was led personally by the Risen Christ.
This is a personality type one would avoid in real life.
And i had already saw for myself that there are quite a few contradictions concerning Him.
So comparing the scripture pointed out to the ones which are common knowledge to those who will acknowledge them does give reason to doubt.
There is no way i would trust any one who will try to slip around or ignore any scripture that does anything but lift their ideal which is Paul.
Many people will glory in the idea that Paul corrected Peter but if it is mentioned that Paul may have not been perfect they will throw a wall eyed fit.
And personally that is what has inspired me to take a good look at Paul who i used to think was the greatest apostle and now not even sure he was an apostle.
