Why do some religions think they are superior to others?

they all profess to have the one true god and all have a path to the afterlife which they all say is the right path, if you don't follow their path then you go to hell so it preys on your superstitious belief by blasting you with eternal hellfire. if your a christian then a muslims evil and if your a muslim then everyone who isn't muslim is evil and if your a jew then you are chosen and everyone else goes to hell, these are the main faiths and are all abrahamic and islam being the later is very clever at expanding, eg. no contraception of any kind, isnt recognised in a healthy marriage and if you should have every 20 days i think or you can divorce, under a sharia jurisprudence muslims can kill, enslave, forced marriage people who arent muslims and they get away with it because they're considered evil, its all power baby.
