By capitalized Justice I mean a spiritual principle according to which if someone is guilty, that is, they committed a grave crime (murder, for example) they must atone for that crime, through a proper penalty (according to the criminal code).
But this worldly justice is a fake, phony and unholy justice since innocent people can pay for crimes they didn't commit (on the basis of mistakes made by the prosecutors both in good faith, but most of the times, in bad faith). And murderers can get away with murders thanks to lawyers that in order to have their client acquitted, they would even undersell their own soul to the devil.
At least we theists (Christians or other similar religions) believe in a Supreme God that will judge all those who made others suffer, both unwillingly and willingly.
And as the Bible says, angels shall come forth and sever the wicked from among the just.
The wicked are those who made people suffer out of of selfishness and wickedness. The just are those who pursued justice.
So my question to atheists is: how can you believe life is fair, since according to your beliefs, there is no justice?
Thank you all for your kind answers.
