That statement is GARBAGE, especially as the deeds attributed to god are so evil!
Lack of education and inability to understand justice, evil and good is your problem.
You see man did evil, man allowed evil and man practiced evil.
God punishing evil was just the same as us punishing evil. Only unlike our human judges he had no sin and was witness to all things knowing all the hearts of those who committed evil and able to see what would happen if he allowed those who committed those evil things to live.
God NEVER KILLED AN INNOCENT MAN. In the bible he had a covenant with the Israelites.
A covenant they agreed to. You have NO right and NO innocence to be able to judge God.
Because you are a sinner and the things you say against God are simply your lies based in your own evil and understanding which the latter you lack in greatly.
Imagine a truck coming at you. Because you walked out in front of it too busy to be bothered to look before you stepped out. You may blame the truck and driver but the truth won't change it is your own fault or stop the truck hitting you.
Unlike you God can see what happens yesterday, today and forever.
He knowingly made all decision in the best interest of the human race. But you can't see beyond your own space let alone give credence to truth.
