Someone who actually cared about his own children wouldn't be capable of saying this shit with so much confidence because they'd capable of seeing other adults and kids as "their own" too, a kind of empathy you can kinda only develop by being a parent.
The fact he uses them more like status quo trophies shows a really disgusting and inhumane side of him. He probably only had children to accomodate a social quota, not because he actually loves them. He doesn't value human life as human, but more like a transaction, a holy duty or even monetary. It's just gross and hard to explain how it feels to hear this dumb motherfucker
Some folks may need to become a parent to develop this form of empathy, but it isn’t by any means required. A ton of the childfree folks I’ve met are extremely empathetic and forward about wanting to better things.
