Gods character in Genesis (Mind map)

I always thought that God was a very nice and helpful person. He was the one who created Adam and  Eve and the whole Earth.  However, after reading some of Genesis I learned that he really wasn't the nicest, unless you consider killing everyone on Earth is a nice thing. But he also helps the animals and Noah's whole family by telling him to build a boat. So sometimes he was good and sometimes he was bad. But then after that he becomes a good guy again by apologizing and saying that he will never do something like this again. But he also helps the animals and Noah's whole family by telling him to build a boat. So sometimes he was good and sometimes he was bad. He realizes this but he doesn't really change it until after he does the bad things. God's personality changed a lot and sometimes he was a good guy and then he becomes a bad guy. He changed from who I thought he was originally but then he chases back to who I thought he had been.
