Is Bible-God loving or a monstrous killer?

The Catholic Church teaches and all Christians believe that the Bible God is love.

How does God’s love operate in the Bible? Throughout the books of Moses we find that God (Yahweh) is to be feared and to be appeased. In the Exodus we read how He punishes pharaoh to let the Israelite go with Moses. God turned all canals and rivers of Egypt into blood. What did the poor creatures that lived there do to die an ignominious death? He then plagued the whole land with frogs, gnats, swarms of flies and locusts. Horrible boils and blisters destroyed everything. His angels beheaded thousands of innocent first born children (there is no accurate count). Pharaoh was afraid and was willing to let the Israelite go with Moses. But in or order to punish him more, God hardened his heart at night. He sent further punishments to the land of Egypt and its  people. At last God let Pharaoh release the Israelite with Moses. He parted the red-sea waters for his people to pass. Seeing the pursuit of the Egyptian Army just behind, God closed the waters on them drowning all the men and the beasts. (See chapters 7-14 of Exodus). 

Even to the Israelite God was a terror.   His punishment was severe to those who disobeyed his commandments. (Deuteronomy-30) “You do anything and you will be utterly destroyed.” “The Lord will smite you with fever, inflammation, drought, boils, fiery heat, madness and blasting until you perish. Your dead bodies will be food to all the birds and beasts.” (Deuteronomy 28:16-25) He frequently sent famines, plagues, hailstorms, and fire to his own people and others (Genesis 26:1, 41; 54:43; Exodus 32:35). When the Israelite made a molten calf He makes His messenger rave: “Now let me alone so that my wrath may not burn against them and consume them in a moment.” (Exodus 32:10)  

When Aron and Miriam turned against Moses, God made them leprous: (Numbers 12:9) Whenever the Israelite grumbled-often for genuine reasons-He threatened to punish them. (Numbers 24:23) When Korah organized a rebellion, God raves: Separate you from them that I may consume them (Numbers 16:20). When the Israelite began to prostitute with the daughters of Moab, God commands: take their chiefs and hang them before the Lord (Numbers 24:4).
Is this the picture of a loving and merciful God?

"I will ... trample them in my fury; and their blood ... will stain all my raiment. God's clothes will get stained with the blood of humans.” (Isaiah 63:2-6). When God gets mad -- watch out! He'll starve you to death, burn you with fire, and send vicious beasts to devour you. He'll destroy both the young man and the virgin, the suckling with the man of gray hairs. Not even the helpless and innocent children are spared. (Deuteronomy. 32:21-26)

God would send false prophets capable of doing miracles to test the Israelite. People would naturally start respecting them. And God would become wrath-incarnated. “If a prophet gives a sign of wonder …you shall not listen to his words. … For your Lord is testing you. You shall be after your God and fear Him.” (Deuteronomy 13:1-5). How could the people know those who performed miracles were false prophets? 

 God demanded animal and human sacrifices from the Israelite. To appease him, to get sins forgiven, to gain favors lambs, goats or bulls had to be sacrificed for Him and their blood sprinkled on the altar of the Lord and the flesh with all fat burned as the smell was most pleasing to this God. Leviticus gives details as to how animals are to be killed, their blood sprinkled and flesh burnt. Human sacrifices are not detailed in the OT but it was not repugnant to Yahweh, God asks Abraham to sacrifice His son for Him. (Genesis: 22:10) Just before Abraham was to slit the throat of Isaac, it was stopped, and a lamb was shown to take his place.                                     

The story of Job is an evidence for the atrocities of God and His complete disregard for human life. The Bible God and Satan placed a bet on whether Job would stop worshiping Him if things started turning wrong for Job. So God killed Job's children, destroyed his house and took everything away from him. As Job did not turn away, He gave him 10 other, more beautiful children. Think of God killing children and then creating more beautiful kids in a game with Satan! (Read the details of it in the book of Job.)

God is an ethnic Maniac

To settle His people He did the most vicious campaign ever known in history. One by one He annihilated the hostile kingdoms of Israel.  “Take all the fighting men to Ai as you did to Jericho … lay an ambush behind the city when you have taken the city fire it as the Lord has bidden.” (Joshua 8:1, 2 &8:8) “Israel snorted until there was none. As the Lord had commanded they hanged the king.” (Joshua 8:26)

“When all the kingdoms came to attack Joshua, Lord threw heavy stones from heaven upon them and they all died.” (Joshua 10:11). God ordered the sons of Levi-Moses and Aaron-and the other members of their tribe that were "on the Lord's side" to kill "every man and his neighbor.And there fell of the people that day about 3000 men." (Exodus 32:27-28) But God wasn't satisfied with the slaughter of the 3000, so he killed some more people with a plague. (Exodus 32:35)

“Makeddah, Jericho and Libna were already annihilated. The same was later done to Lachish, Horan, Eglon, Hebron, Debir, Nageb”(Joshua 10:31-40) “When a host of enemy kings came to confront the divine army, the Lord God said: do not be afraid of them, tomorrow at this time I will slain all of them for Israel.” (Joshua 11:6)
The details of such ethnic cleansing are in the books of Isaiah, Jeremiah, Ezekiel, Amos, Zephaniah, Exodus and Deuteronomy.

“Only in the cities of these people that the Lord your God is giving you as an inheritance, you shall not leave alive anything that breathes. But you shall utterly destroy them: the Hittite and the Amorite, the Canaanite and the Perizzite, the Hivite and the Jebusite as the Lord your God has commanded you, so that they may not teach you to do according to all their detestable things which they have done for their gods, so that you would sin against the Lord your God.”(Deuteronomy 20:16–18) 

Only an ethnic maniac can think and act like the Bible God. See His command: “Thus says the Lord of hosts, ‘…go and strike Amalek and utterly destroy all that he has, and do not spare him; but put to death man and woman, child and infant, ox and sheep, camel and donkey.” (I Samuel 15:2-3) God killed/destroyed many of the  kingdoms of Canaan to settle to His bosom people. 

God destroys everything 

When the sons of god saw that the daughters of men were fair, they took to wife such of them as they fancied and the Lord was angry and he punished man and fixed his life-span as 120, Later,
God destroyed the entire human race in a huge flood.. God killed everyone in a single stroke. In genesis we also read how God annihilated Sodom and Gomorrah  with fire and brimstone from heaven with all the toddlers, infants and the newborns, the crippled, the aged, and the sick.

The Bible God is simply a killer-god.
