The strategy for male rodents is to kill any young they can up until the point that they mate. Then they no longer kill. The reason is that there is a 100% chance before mating that the offspring are not theirs.
By Hamiltons Rule, since relatedness is nearly equal to zero, the benefit must also be near to zero as well. On average a male rodent will benefit by this tactic to pass their genes onto the next generation. Inclusive fitness dictates that the selfish genes will work the percentages from the standpoint of relatedness. I don't think it makes any difference whether the offspring are female or not. Female hyenas will kill off their litter mates in order to dominate their cohort.
In humans, the practice of female infanticide is not uncommon, but this is mostly due to socio-economic reasons. Infanticide is most common with young women with low access to resources. In Victorian England there was a rash of impoverished women "accidentally" rolling over their babies in their sleep. So a law was passed that forbade women from sleeping with their babies to prevent "accidental" deaths to the babies. Ever since, Anglo-American women sleep separately from the babies.
