I have been treated unjustly.
God is not neutral about this. The prophets are loud, specific and angry about people being cheated, and the command to do justice sits beside the command to love mercy. Two things go together and neither cancels the other: pursue justice by every lawful means available to you, and refuse private revenge, because vengeance belongs to the One who will not make a mistake with it.
Go and see for yourself
