Salaam,
Who ever said that people of this or that religion will go to hell(It is up to Allah), its about your deeds at the end of the day-if you didnt know that this or that was haraam(forbiden) you wont get the sin for it.
Second off, RIGHT NOW--i have all the resources i need to look into almost ALL THE RELIGIONS and then base what is right and what is wrong, now if someone who is LAZY and does not want to investigate into Islam, or christianity or whatever, thats thier problem, and frankly if your being lazy about your ETERNAL AFTERLIFE, then thats your fault, period.
ALLAH SWT is the most forgiving!!!! ok you cant say who is going to hell or not. who ever said that you are born into the wrong religion and you go to hell, i mean PEOPLE CONVERT....becaue they are not being lazy and have found out errors in thier way of life.
now you might say what about sins that can not be forgiven SHIRK, well lets think of one shirk, claiming partners with God, aftagfirullah, now you claim God(s) and i think you assume that Hinduism claims that right? well in actual fact if you had studided the different religionns then you would know that in hinduism thier is one God--who has no images, now that shows that even some people within thier own religion dont know about thier own religion. watch Concept of God in major religions by Zakir Naikplus most of the respected religions belive in monothieism. so that shirk is ruled out.
look you say you was "I was always uncomfortable with the idea of hell." well think of this thier are people who disrespect God i mean look at this guy
