Deuteronomy 24:16, "The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers: every man shall be put to death for his own sin."
What is God there for? To conquer and remove the only barrier preventing a personal relationship with Him. That would be the conquering and removal of sin.
John 3:16, "For God so loved the world, that he gave His only begotten Son, that whosoever believeth in Him should not perish, but have Everlasting life."
So blame God if you want to, but you are blaming the wrong one. Sin and its followers come from the devil. The world's problems are not caused by God, they are caused by evil.
And last but not least, John 10:10 "The thief cometh not, but to kill, steal, and destroy: I am come that they might have life, and that they might have it more abundantly."
