Christianity seems to center around the idea of who's going to heaven and who's going to hell, but that's not the case with Judaism. (I can't speak for Islam.) It's true that "the wrath of God" is detailed in the Jewish texts, but I've never heard it mentioned as a means to frighten people. If you're Jewish, the interpretation is one of history; that God made a contract with the Jewish people, then did these things to save them from enslavement. Sure, the Jewish people screw up and incur some of God's wrath, but it's nothing like suffering in hell for all eternity. The interpretation I learned was that God's feats represented God fulfilling His part of the contract, and now it's our turn to fulfill our part. There's no threat implied in any of that, it's just stated to show that something was done for you (through your ancestors), and now you have a responsibility to uphold.
Another big difference between Judaism and Christianity is in personal responsibility, and the purpose of life. Christianity seems to dictate that we're all powerless vessels floating on a sea dominated by currents of good and evil. Satan lures you one way, but you need to believe to be saved and reach heaven. The purpose of life is simply to find that belief and stick with it, avoiding the temptations of Satan. By comparison, Judaism focuses on more "practical" things. According to some texts, God left Earth to Man; that is, we're tasked with turning Earth into a paradise. Satan exists in Judaism, but he isn't a source of evil. Rather, the belief is that when you die, your soul goes before a "spiritual court," where Satan is the prosecutor who points out all of the evils that you committed. Basically, while Christianity views evil as some external force, Judaism recognizes that evil can come from within, and claims that everyone should take responsibility for it themselves.
Honestly, it all sounds pretty silly if interpreted in a literal manner. Being Jewish (although "spiritual but not religious") I am obviously biased, but one of the things that I really appreciate about Judaism is that it seems designed to be a guideline to living and finding meaning in life. The focus is on being a better person, improving the world around you, appreciating and enjoying your life. If you can do all of that without reading the Bible or praying to God, wonderful! Formal religion may not recognize you for it, but there's a line in the Bible which claims that you would be considered Jewish simply for that. This is one reason (among others) why you don't see Jews going around trying to convert people. Not pushing the beliefs on people, I might add, is another appealing factor to the Jewish belief set.
TL;DR: What you say accurately describes most forms of Christianity, but there's at least one religion (Judaism) that doesn't quite fit it. I don't think anyone needs religion, but please keep an open mind and don't condemn all religious beliefs just because Christianity can get a bit nuts.
