There is nothing in the Gospels to suggest that God causes the mob to come together against Jesus. Violent contagion is enough. Those responsible for the Passion are the human participants themselves, incapable of resisting the violent contagion that affects them all when a mimetic snowballing comes within their range, or rather when they come within the range of this snowballing and are swept along by it. We don’t have to invoke the supernatural to explicate this.
