For one thing Sodom and Gomorrah had no knowledge of God’s plans thru Jesus and the Kingdom. The Jews at Jerusalem did know about Jesus Kingdom and the Jews rejected it, most anyway. So Sodom and Gomorrah people who get a resurrection to Judgement will have more going for them than the Jews who rejected Christ. The Spiritual leaders especially will have that heavier judgement. Just like the GB Members are going to find out someday.
