@Soul: Judaism itself started as a trauma reaction. The (ancestors of) the Hebrews were a branch of Canaanites/Sumerians (cf. the Bible's reference to "Ur of the Chaldees" and Abram being one). You can think of it as a type of Bronze-Age liberation theology; there is the same element of turning around a horrible situation into something like "well actually God chose us because we're just better despite what we suffered!" That kind of thing inevitably leads to genocide once the oppressed group frees itself from its shackles; human nature being what it is, slaves very often don't desire freedom but slave ownership.
As it is, we now know the Exodus never happened, so the foundational myths of Judaism are either false (Exodus) or cribbed from earlier cultures (the Noah's Ark story is a retelling of the Atrahasis/Ut-Napishtim myth, Sargon was found in the bulrushes before Moses, etc).
Yahweh himself existed as one of the pantheon at Ugarit, and there are stone tablets which read "To Yahweh and His Asherah" in abundance. The words that usually appear as "groves" or "pillars" are actually "Asherah" in the singular or plural. Remember, to Bronze-Age people, gods were local foci of divine power, who each had home bases and spheres of influence; we even have on record, in 2 Kings if I remember right, Yahweh's Israelite army losing to the soldiers of the pagan god Chemosh, after the pagan king powered Chemosh up with human sacrifice no less!
Judaism took a long time, arguably all the way until the Babylonian Exile, to become truly monotheistic; before this it was henotheistic, where other gods were acknowledged, but Yahweh explicitly stated to be the strongest and Israel's patron/only/chief God. Post-Exilic Judaism is basically Zoroastrianism rewritten anyway, as Judaism had no idea of eschatology or reward/punishment in the afterlife before then.
All the ingredients for a toxic, perpetually-genocidal religious mix are thus gathered together: born in pain and rage, in an era of widespread brutality, conquered over and over again, delusional in the extreme each time and seeing it as some kind of mark of divine favor, and then syncretized with another religion that in no uncertain terms preached The End of Times and a hideous doom for all evildoers--define "evildoer" as convenient--and you can see what a mess we have on our hands.
It only got worse when the Romans destroyed the Second Temple around 70AD. Whatever Jesus believed in, he was no Christian as we would understand the term, and indeed even the idea of three coequal parts of the Trinity, the Athanasian view, was chosen for politically-motivated reasons at Nicaea in 325AD on Constantine's orders. He was a devout Jew, for example enjoining in Matthew 5:17-20 that all 613 mitzvot of the Mosaic law be upheld, and firmly believed that "there be some standing here who shall not taste of death before the Son of Man be come in glory." In other words, he was on fire with the idea that the end of the world was coming Real Soon Now (TM). Well, some 1990 years later...
I'm not even going to get into Islam. It's lunacy, plain and simple. Mohammed was a pedophile, a racist, a warmonger, and unfortunately also a master propagandist.
