Will every none christian go to hell?

now i'm not going to lie, i despise religion, i think it is the single worst thing to happen to man kind, but can you please tell me, what will happen to the billions of chinese who have never heard of jesus? will they burn just because they have never heard of him? and gandhi, is he burning just because he didn't believe in jesus? and what about those child molesters who the catholic church helped stay hidden? will they go to heaven because they have took jesus into they're heart, its things like this that makes me not believe in god, i have met good christians diagnosed with horrible diseases emphysemama, heart disease, diabetes, and they adore god, but i am not a christian, and nothing bad happens to me, obviously i have bad luck, but i figure i'm ok with that, because my troubles are nothing in comparison with other peoples, how can god let this happen? and it isn't free will, people don't choose to have diseases, and not just christians, every religious person, will they burn?
