It's the dad's fault for sure. Your children look up to you to guide them, especially boys but even more-so girls. He was obviously a race cuck. He failed her. Yes, there are cases where the daughter does things out of spite, but this doesn't look like one of them. She trusted her own father's intuition (which was bad and influenced by dirty kikes) If you are close with your kids and teach them by showing them (today you need to literally show them videos and examples of the countless niggers who have killed white women) they will not end up like this.
