You have to differentiate between the old and the new testament in Bible. God is good and caring derived from the new testament where Jesus God's son ultimately died for all our sins.
In the old testament God was hard and judging heartless, killing his creation through flood, wanting sacrifices, killed 1st borns, leveled two whole cities Sodom and Ghomora, and was in general an hardhearted God that you should fear.
