Why do children have to pay for the sins of their fathers/parents.  The child was not present when that sin was committ or the child was not the one that committ the sin so why is it that they are the one that need to pay for it?

Every person need to be responsible for their own, they should pay for their own sin and not be passed down to their children.  This is one thing that I dont get about God, why do the children have to pay for it? I should not pay for the sins of my father and neither should my daughter have to pay for my sin.

This is just something that I need to get out of my chest………
