I think it's terrible when people use corrupt paraphrasing of scripture in place of a real translation. God can't be pleased with the distortions of His word.

(1 Corinthians 13:4-8p NIV) Love is patient, love is kind. It does not envy, it does not boast, it is not proud. {5} It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. {6} Love does not delight in evil but rejoices with the truth. {7} It always protects, always trusts, always hopes, always perseveres. {8} Love never fails.

The other thing is that the way God tells us to treat others isn't necessarily the same way that God interacts with mankind. God's greatest desires are for our salvation and for the believer to become like Christ. Both goals can require us to experience suffering. First for us to turn to God in the first place. Second to grow spiritually.

Next, we know that God keeps a record of wrongs. And that it's right for Him to do so:

(2 Corinthians 5:9-10 NIV) So we make it our goal to please him, whether we are at home in the body or away from it. {10} For we must all appear before the judgment seat of Christ, that each one may receive what is due him for the things done while in the body, whether good or bad.
