So basically you went headfirst into breeding with no training or experience and killed a bunch of snakes in the process. A+ job.
This is why we need rein in the breeding trend. These inexperienced keepers think it'll be cool or profitable to breed snakes and have no idea what they're doing which just leads to dead snakes or snakes with issues that end up being sold and bred to create more issues. The fact that you're so okay with just one surviving baby is disgusting to me.
And no, we're not "jumping on you for doing something differently". We're jumping on you for doing things that endanger living animals. Snake keeping isn't art, you don't get to have your own unique spin on it. They have very specific needs and if you don't meet them properly you don't deserve to own snakes. Your mishandling of this clutch and the fact that you feed live despite knowing it poses a danger to the snakes is absolutely unacceptable.
