Step2247 [10]

Explanation:

Pride is the social community of lions where they grow, mate, reproduce, communicate, hunt etc. When male lions gets control of a new territory or a pride, they most of the times kill the cubs of the pride because they are not biologically related and do not want to waste their energy by ensuring that the cubs genes are passed on.

They don't want to be stepfathers. Female lions also will not be responsive to mating during the time they are feeding, so killing the cubs allows the male lions to reproduce.
