You don't have to verbalize judging for it be a sin. For in the same way you judge others you will be judged. And with the measure you use, it will be measured back to you again. In fact, life is too short to hate anyone and if you hate anyone, this verse says you do not love God. Hatred is self-punishment.
Hatred paralyzes life while virtue-love releases it.
Hatred confuses life while virtue-love clarifies it. Hatred darkens life while virtue-love illuminates it. Hatred is a boomerang which is sure to hit you harder than the one at whom you throw it. Our mental attitudes control our lives. Once we believe that all things work together for good for those who love God, then we accept each experience that we face as something that ultimately leads to our own good.
