DoubleNaughtSpy - Yes, there is Darwinian selection here for at least 2 reasons.
1. Whether he has children or not, he will not be contributing any more to the gene pool.
2. If he has children, their survival chances may have been slightly reduced. Therefore, their chances of gene contribution might have gone down.
Darwinian selection is not about all or nothing with just one sample, it is a generalized statistical winnowing with the population as a whole as the level of analysis.
