Why does God Kill Babies

[BlackSwordsman]

1. 1 Samuel 15:3 God commands the death of helpless "suckling" infants. This literally means that the children god killed were still nursing.
   
2. Psalms 135:8 & 136:10 Here god is praised for slaughtering little babies.
   
3. Psalms 137:9 Here god commands that infants should be “dashed upon the rocks”.
   
4. Leviticus 20:9 “For every one that curseth his father or his mother shall be surely put to death: he hath cursed his father or his mother; his blood shall be upon him.”
   
5. Judges 11:30-40 Jephthah killed his young daughter (his only child) by burning her alive as a burnt sacrifice to the lord for he commanded it.
   
6. Isaiah 13:15-18 If God can find you, he will “thrust you through,” smash your children “to pieces” before your eyes, and rape your wife.
   
7. Mark 7:9 Jesus criticizes the Jews for not killing their disobedient children according to Old Testament law.
   
8. Proverbs 13:24, 19:18, 22:15, 23:13-14 & 29:15 God commands repeatedly that you beat your children.
   

I don't know just looking for justification.

Do not use the bible to justify your answer
