On the other hand, silverbacks have been observed to deliberately kill babies - especially in mountain gorillas. Usually this is the case after a female transferred to another male together with her baby or if a new leading male takes over. This behaviour, called infanticide, is interpreted as a means to shorten the time until the baby's mother becomes fertile again and the new male can sire his own offspring with her.

In many past societies, certain forms of infanticide were considered permissible. In India female infanticide is more common than the killing of male offspring, due to sex-selective infanticide. In China for example, the sex gap between males and females aged 0–19 years old was estimated to be 25 million in 2010 by the United Nations Population Fund.

So then according to your logic human beings also don't have any moral values because they also sometimes kill their infants. Not to mention your god that you worship so dearly:
you will eat the fruit of your womb, the flesh of your own sons and daughters Deuteronomy 28:53

Their infants will be dashed in pieces  Isaiah 13:11–18

slay both man and woman, infant and suckling 1 Samuel 15:2–3

smote he with the edge of the sword, both men and women, children and sucklings 1 Samuel 22:19

their infants shall be dashed in pieces, and their women with child shall be ripped up. Hosea 13:16
