I think the thing with Columbus is that somebody was gonna get there eventually right. like the Portuguese in particular had spent a lot of resources exploring the east and Africa before the discovery of the Americas. I think you're better off helping spread cow pox, as it's far less deadly than small pox but provides immunity to smallpox which is what killed far more native peoples than guns and swords did. but I think you should still kill Columbus anyways because he fucking sucked and was 🤮 It*lian
