How did the Judeo-Christian God go from a blood tasty deity to the loving one we have today?

Your question's answer entails the entire Bible. Why don't you sit yourself down and study this out on your own? Perhaps you will stumble upon comprehension of God's attributes and not focus solely upon one or two of them. Do not settle for pat sound bytes from atheists, dig out the truth from within the Bible. Holy God is not some finite guy from down the street who does the exact same goofy stuff that you do.

Your statement about Jesus indicates your lack of understanding that Jesus is God. If you can not comprehend what sin is all about, then how can you charge God with doing "gruesome stuff" in response to sinful acts? Wrap your mind around what sin actually is, then begin pondering what the response of a holy, just, righteous, Being would be to it coming into His presence? What is the proper response of such a Being to it's creations refusing to believe that He has told them the complete truth?

Supernatural stuff happens every day, you just are not aware of any of it. Each time someone's life dramatically changes upon accepting Jesus Christ as Lord and Savior it is a miracle. God declared that He was done doing supernatural events until the the Great Tribulation Period comes at the end of this age. He has no further need to interfere in human history until the appointed time of the End of Days.

God is 7 who are 1, it is very important that you understand that, look up the word "Elohim" which refers to the different aspects of God.

The one that the Israelites saw in the old days was probably Samael(Otherwise known as the angel of death or according to some kabbalistic sources the "severity of god")

Christ may be the son of god, but to equate him with god the father is foolish.

"Be not deceived; God is not mocked: for whatever a man sows, that shall he also reap."-Galatians 6:7

You ask a intriguing question and one that I haven't completely worked out but I will tell you what I think for what its worth. First off God doesn't change but how He deals with us and sin has. From the garden where it all went bad until today our history with God has been Him loving us despite our sin but yet as we would a wayward child, still not allowing what is bad and detrimental to us by exacting consequences so as to show the error of our ways or withholding blessings or rewards given when we are doing what is good and right. This is still going on today you just don't realize it because the devil deceives us, makes us blind to the fact that EVERYTHING is a cause and effect of our spiritual mind set. The wars we've entered into and won or lost for instances was absolutely spiritually influenced based on what our motivation as a nation was and what we were to learn by it.

After Jesus was born and died another era as to the issue of sin was entered into, all the laws that needed keeping in order to stay right with God and which pointed to what Jesus was going to do were done away with because now Jesus had done what those back then had to symbolically act out by the keeping of the "law". The Holy Spirit was enabled to be sent to each of us instead of one person in a burning bush. He quietly deals with our conscience and points us in the right direction but believe me the consequences of sin are just as deadly as they ever were and the rewards for worshipping God and trusting in His love for us just as great. Its much much easier to actually be "saved" however for where actions counted in the old testament, all we have to do is ask and the free gift of salvation and forgiveness is given because of what Jesus did for us on the cross because of our need to be saved from a everlasting death due to our sin.

From its inception, when Christianity gained power with the imperial court, from 314 AD onwards, it started destroying its rivals, first the Donatists and after 380 AD, the Arianism.

For the next 2 centuries till 580 AD, it had been intent and focused on exterminating all the pagans and believers of other religions to the extent of burning off all books that were non-Christian related. The destruction of whole cultures of diverse European states took its toll and from 4th century to 15th century AD, it was known as the Dark Age of Europe feudalism. The masses were yoked under terror, subjugation and ignorance and heresy hunters, witch burners, crusaders, and inquisitors made their presence felt to terrorize the population into devotion to the only acceptable religion and its dogmas.

Its intolerance drove some of the bright intellectuals to the safe sanctuaries of Arabic nations of Syria, Saudi Arabia, etc and these learned men translated Greek and Roman texts (philosophy, Science, architecture, etc) and Nestorian and Arian gospels into Arabic . . . thus launching off the flowering of another culture while Christendom Europe was yoked under the darkness of feudalism (with its rampant and pervasive abuse of women and children by the churches, as it came with property, the church, kings and lords owned almost everything).

It was the Mongol conquest, Black Death and the Ottoman invasion and capture of Constantinople in 1453 AD that loosened the shackle of feudalism and ushered in the age of Renaissance to Europe. However, the church still had ultimate power (King Henry of England managed to break free from papal control by forcing the separation of church of england). With such prevalence of corruption by the church, opportunists started the Reformist movement and cause a split. Yet, the catholic or the reformist churches did not propagate nor disseminate its true message of love. It was political power they sought all along.

It took an atheist, Spinoza (who was ex communicated for his writings) to write about an impersonal god and nature and god being one and the same thing. His writings inspired generations of writers (from Marx to others to start writing and recognizing some early forms of human rights, freedom and democracy).

Revolutions occurred (Glorious Revolution, French, Bolshevik) and the last vestiges of feudalism was destroyed in 1917 by the Bolshevik Revolution.

In the passage of history into modernity of liberty, freedom and human rights, the church played no part in it. On the contrary, it was the hindrance and the evil (of Christianity) that ensured that the masses stayed ignorant and subjugated to a higher authority. Is that LOVE?

Look at the torture machines/devices that ensured compliance to the imperial religion, and you will understand how Christianity 'dispensed' its love:

Cherry picking only the good parts of the Bible. Which is apparently a 100% correct source of morality...

He did it out love for his chosen people...he didn't want them corrupted by the evils that were in the world at that time and are still here...God hasn't change the evil has. No hope without jesus.

God loves you.....

He got laid by a 12 year old Jewish girl.

the people who invented god were not nice people

but then the people who wrote the new testament said we had better make him a more friendly god

what do you mean? God is unchanging. Jesus Christ, the same yesterday, today and forever.
