Why didn't he kill the baby?

He's supposed to be "pure evil" so why didn't he kill this baby when he had nothing stopping him. He even stops to give it a look before walking out of the house after murdering it's mother.
Don't say it's bc people wouldn't have liked to see a dead baby, if that's the reason they would've just not included a baby at all. They wanted this specific scene so why?

SKIP TO SCENE 1:30
He has a little heart
It was pointless to him
