Claiming Christianity gives you a free pass to do all the sinning you like.......it gives you a perpetual excuse for your inhumane behavior........which is why Christianity attracts dysfunctional sociopaths.....
The fundamental premise of Christianity is that humans are incapable of being perfectly righteous by our own actions - which is why we need a Savior. That is also why the New Testament is a covenant of grace (unmerited favor), and explicitly not law (a list of rules to follow). So anyone who interprets "Jesus' sayings" as law (as you appear to be doing) is missing the whole point of Christ's gospel and passion.
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.
