So your puny god was so afraid that babies would grow up and some of them might threaten one of Jesus' ancestors that he had all of them murdered while they were still helpless infants.
If you believe God knows the outcome of every possible event then he would know that those babies would grow up to threaten the bloodline. It's nothing to do with being afraid. He would have known for a fact what was going to happen if he did not do exactly what he did.
Yes you did.
No, no I didn't. Neither does the article. It states several combined factors would have led to damaging the bloodline.
