Since one can always confess their sins and be forgiven, isn't Christianity/Biblical law basically useless?

With some people, the notion of them being in heaven would be simply absurd, for example Hitler who slaughtered millions of the "chosen people" - at the same time, without exception it's not our place to judge. So while it may seem obvious that he was an evil man, it's not my place to say "he will burn in hell", if it were he'd probably be top on my list (right above the Kardashians and Phil Jackson and the LA Lakers, ect) - but it's not my place to judge (even though in jest I just did). So since we can't judge, we shouldn't exclude people from heaven by denying them a chance.

So do I think Hitler will be in heaven and fully forgiven - certainly not - however I won't step into God's shoes and pretend that it's my place to tell him where he's going to wind up.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
