there is certainly too much of this these days. I can only speak for myself but I try to live my interaction with others in a more libertarian manner, while trying to hold high moral standards for myself, but I fail regularly. I particularly struggle with attempting to balance what I believe my religion teaches regarding raising my family with the faith, while still respecting their rights and autonomy as individuals.

Including whether hell even exists

No there isn't, the islamic scriptures are very clear about this

If by "the biggest group in her religion" you are referring to the Catholic Church, that's not true. While it certainly would be a mortal sin, really all of Protestantism is heretical, but the Chruch does not condemn any individual to hell. In fact, as St. John Paul the Great tells us "We know that hell exists because Jesus told us it does, but we don't know for sure if anyone is there" If she was unrepentant prior to her death, she would likely spend some time in purgatory, but I suspect less time than I will spend in purgatory, as I should know better to avoid serious sin than she does based on her raisin'.
