I would not do so even if I had the option. I do not care if I can kill children or not. To me it would be way more immoral to shred a painting that has lots of labor put into making it than shredding a blank piece of paper.

thanks to the mankind's labor we got life standards that would be unthinkable hundreds of years ago and most of us don't really think of it. To me moral is respecting mankind's labor that translates to money. I would say that the statement saying 'children are more precious than adults' is false In the cyberpunk world human life would be valued by the productivity (how much money it makes per day minus the investments it takes and how much it contributes to making money, for the corporation for example) which would obviously be much higher in the adult's case, which would make children lives not very valuable resource in the world of cyberpunk. it takes few years to replace a baby that died but it takes few times more time and even more times the money to replace an adult that died. you can think of children like blank pieces of paper that are not nearly as valuable as painting that has a lot of investment put into.

If you look at it from purely logical perspective, children are quite renewable resource because of how little investment was put in them compared to adult human that was educated and some company put a lot of money into him if he's a worker.
