As an atheist, I consider all humans to have equal value, and also consider animals to have value. (Much as I love other animals I would assign lesser value; I eat meat, wear leather, and support medical research.) That means even those I most loathe, deservedly, should not be raped, starved, tortured - even if I think they deserve punishment in prison or by making restitution. It also means we are all (except very young children and those too mentally disabled to be able to make choices) responsible for what we do. I can't do something shitty and then say oh well if I pray god will forgive me and even if the other person has been not just hurt but has had their entire life irreparably damaged, well, they just have to forgive me whether I apologize/atone or not. Maybe one of the reasons why atheists/agnostics are under-represented in prison.
It also means we get one chance and one only. So if I see something that needs doing or fixing on earth I have responsibility to do what I can. I can't say oh well the unjustly harmed, the Salvadoran woman Sessions just sent back to be raped, the children torn from their parents, the homeless, hungry, abused, will get bliss in heaven if they pray the right way. Or that some day G-d will bring the World to Come. Or that the victims deserve it because they didn't pray the right way and will get further punishment after death because of it.
My biggest disagreement with Christianity (aside from the not so minor detail that I'm an atheist) is the notion that god can forgive anything if you have faith. In the most extreme case, and yes I have more than once heard self-identified Christians say this, if Hitler accepted Jesus in his last second on earth he's in heaven. The millions of Jews, Romas, gays, socialist, anarchists, etc he murdered are all burning in hell. Believe it or not this has been said to me as a way to get me to convert. My answer is that when Hitler killed people their misery anyway was over but I am supposed to worship a god who tortures them for eternity? A god who hates Jews worse than Hitler?
Sorry about your friend, riverman, I can see how tough it must be to plan a social engagement with someone and instead they commit suicide - you are not responsible.
