What i mean with the title is: Mothers often feel as if they can’t be successful themselves, due to their role as a mother. So, they try to make their child(ren) “successful” in their place. What that entails is a strict, hierarchical upbringing and a lot of “discipline” for the child(ren). As a direct consequence, the child(ren) have significantly reduced Quality Of Life, to the point of many committing suicide, and as such they are definitely a thing that can end lifes, or personal worlds (for the children). As such, they are clearly one of the “horsemen of the apocalypse”.
