God kills a child for the sin of the father

[Esquilax]

David is the king of the land, his transgressions are the peoples transgressions, just like if Obama were to bomb some random country, the country would hate America not Obama, and would wage war on us not the president, it's the same thing, and if you read the verse, it says God had given the country a sickness from morning to night, and felt he had given enough punishment, and pulled the angel of death back before he destroyed the nation, God is not vengeful but merciful and great,

Plus the rules told us not to ridicule the atheistic belief, but how come you guys can straight up downgrade Christians without punishment? But still I will turn the other cheek, and forgive ou of your doings

So, who consented to give god the right to punish people?
