You're confusing final vengeance upon evil with the church's mission to be Christ in the world. No righteous man was more defrauded, abused, betrayed, slandered, and unjustly committed violence against than Jesus. By wicked, corrupt, evil, hypocritical cabal motivated by holding to their religious and political power. So why did God let that happen if He ever and only destroys evil? Why did Jesus specifically train and warn his disciples before their final visit to Jerusalem that all the chaotic events that would unfold for the next week would be exactly according to plan, and that he was in control the whole time? And why did the first Christians find it virtuous to follow in Christ's steps when it came to repaying evil with good?

I think what you mean to be referring to is not tolerating victimhood culture, which we should all agree. We live and breathe an era where simply being a perceived victim of anything or anyone is by definition a virtue. This is not what Christianity espouses. Christianity teaches that bearing the sufferings of persecution injustice and evil ought to be avoided and resisted as much as ethically possible, but not to take divine judgment into one's own hands. Paul reminds the church that doing good to those who slander or do evil to you, is actually heaping burning coals upon their heads -- i.e. compounding their legal guilt in the final judgment they will face if they continue unrepentant.
