I’d actually argue the opposite. Religion reigns in bad people. Talk to a religious person, wait until you hear them say something like, “but if there’s no god and no afterlife, what’s to stop people from murder and rape?” That’s all that’s holding them back from total anarchy, the threat of eternal suffering and damnation, only for some it’s still not enough.
I apologize in advance of the things I am about to say to you but this has to be one of the most naive and sophomoric statements I have ever read, so I’m going to address you as a teenager because I hope nobody gets to adulthood believing such bullshit.
To start with I hate to be the bearer of bad news but a substantial percent of humans are violent by nature, which means there is no amount of logical debate that will convince someone to not take your things or your life. This transcends to the national level which is why every peaceful nation in history has an army, for self-defense.
Army doesn’t make any productive labor? My brother in Christ you are on the internet. Which means you are using a software that implements TCP/IP protocols specifically designed to build the . . . Drumroll . . . ARPANET! For the US military? Did you type that comment with your phone? Did you use GPS today? Hell the entire space race was funded for military reasons!
I have to envy you though. Thinking that you can simply argue your way out of any confrontation without the threat of violence, must be nice. Ask Palestinians or Ukranians what they think of that.
