You can probably put a delay according to their birthdate to make an abortion. I'd be only troubled how a chain of deaths can cause a butterfly effect on the situation.
Also, if DN's effect is imminent, could it also prolong life by setting it decades after?
Series aren't liked for being smart, but it's interesting to explore these terms.
The rules of the death notes generally have time limits in the tens of days. They can only control+kill a person for 23 days, and the pre-filled death methods (such as how Light killed Raye Pember) are said in supplementary text to only work for 19 days.
I imagine that first clause would prevent any significant life altering shenanigans.
That's an interesting thing I didn't remember. Thanks.
I'd wonder how much of the rules are actually true and if Ryuk tested Light if he can break them. One of things he did is letting not-owner fill the names of the agents in the blank form and using torn pages. Although it isn't condemned, it's half-right. The not-owner wasn't contacted by the God of Death and their code seems to be inclining that, as using one of such devices is basically a deal with the devil. I wonder if it can be pushed further.
