Your simplistic view of the biblical God is woefully inadequate. As Dicky Underpants wrote in an excellent comment recently, the picture of God develops. God is certainly a pretty unpleasant character in the earliest books of the OT, but by the time we get to the prophets, we have a God of justice and mercy, who enjoins mercy on us. "What does the Lord require of you, but to act justly, love mercy, and walk humbly with your God?" "And many people shall go and say, Come ye, and let us go up to the mountain of the Lord, to the house of the God of Jacob; and He will teach us of His ways, and we will walk in His paths: for out of Zion shall go forth the law, and the word of the Lord from Jerusalem. And He shall judge among the nations, and shall rebuke many people: and they shall beat their swords into ploughshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more." –Isaiah 2:3–4
In the |New Testament, we have the father of Jesus Christ, a God of forgiveness and mercy, the God of the beatitudes, a world away from the cruel tribal god the OT starts out with. It's much more complex that "the god character in the bible is an evil psycho imo", so try actually reading the whole of the bible. (Incidentally, there's not really any support, in either Testament, for the traditional concept of hell as everlasting, conscious torment. The fate of the unsaved is annihilation.)
