[Why does God let us suffer so much? Every five seconds a child dies of hunger, why?]

God doesn't let us suffer so much. What you are dishonestly passing away here, is that _suffering_ is the consequence of a PERSON doing an injustice to another person, for instance some other person sleeping with your spouse and giving your spouse some kind of disease, _suffering_ is a consequence of choosing the WRONG things. Take accountability for your actions and hold yourself to a higher cause, God, than oneself.
We all will die, so are you saying that DEATH is suffering? You make no logical sense, zero! I pity your lack of depth of thought!
