According to DNA evidence at least 13 of the children there were Koresh's including from females who would have been underage at the time they conceived. Name a cult leader who isn't a pedophile.
What they did was fucked up and led to the unnecessary and avoidable deaths of a lot of people but that doesn't mean Koresh wasn't a scumbag. And to be clear, they shouldn't have even been involved. They should have left it to the more competent local authorities to handle a local problem under state law, not barged in over weapons shit that was exaggerated at best and outright fabricated at worst.
