i got that you do not like religion and its practices , but same zealot methodology can be applied to you , are you willing to put a what if terminology to the same conclusion you have drawn "religion sucks"

may be you are wrong , may be you have not looked hard enough , may be you did not got a good teacher ..

God has given us freewill to choose (what we like) and soul as a moral compass ( but its get corrupted as one get old) and judgement will be done on the abilities we got and situation we found under; there is no guarantee who will get heaven and hell.

religion is an added path way provided to human (ones a soul reaches a conclusion that God is one and he is the creator and sustainer) to find practices that are necessary to know more about God , here after and a to create a balance society and individual

another thing to consider is human have failed to provide an alternative to religion (doctrine) , last two war has been fought by nations which are mostly secular democratic/communist and same goes for capitalistic societies who has ruined the planet and we are on the verge of climate catastrophe or if not than war is imminent between china and west or Russia vs NATO

I cannot speak for other religion but in Islam there are few things which cannot be question ( its not like there is rationale explanation for them) and few thing are open to consensus ijma and qyas (https://www.ukessays.com/essays/religion/the-four-main-sources-of-islamic-law-religion-essay.php) , its perfectly fine if one set of people reach a different conclusion vs the other

unfortunately Muslim world has stopped reading and learning and are backward in both secular sense and religious sense so you will find all this non sense but Islam has all the ingredients to provide humanity with a balance (not unjust to one group) way forward where every one can live in peace
