For example, in the early days on life on Earth about 98% of all life was wiped out due to oxygen pollution. There are probably x number of planets for every Earth were the fatality was 100% and they are now just toxic wastelands.
I suspect it's something like this. For everywhere that life is a non starter there's also probably a world where it doesn't evolve recognisable complexity and remains as small aggregations of organic molecules.
The other thing is like, why is it that life on earth managed to proliferate at all? One of the current ideas is that it formed from like lightning striking a stagnant pond full of organic molecules, catalysing a very energetic reaction. A rare event sure, but not so rare that it wouldn't have happened a few times. How did these molecules spread across the earth? Surely there must have been times where such life precusors simply dried up and "died" when their ponds wasted away.

Permian mass extinction was probably the closest it last got to something similar, and I doubt humans will be able to replicate something of that scale
That being said people are capable of some big gooseberry fool lmao so we'll see
