So what exactly happens to sinners and the unrepentant? Because Yahweh was rather unforgiving and generally had the mindset of "Hey, you. I don't like you. I'm gonna send my chosen people to be Dalek stand-ins and wipe you out".
People compare God to being the most perfect, loving parent.Traditional Christian, Jewish and Muslim culture, apparently.
I want to know in what culture locking random kids inside a box filled with sharp stabby things for all eternity simply because they won't call you "Father" and adore you and lick your boots is considered "good parenting".
Not Jewish. We don't believe in Hell.
If I understand correctly, even though Judaism "officially" has an afterlife, it doesn't have any unified idea of what that afterlife is. Unlike Christianity, which emphasizes "securing one's place in Heaven," Judaism doesn't talk about it that much.
Anyway, you could probably search the internet for Jewish sites that explain this better, but be prepared to get wildly differing answers.
