Yes, I agree with the verse. However, I do not agree with your personal interpretation.
Useless or unjust revenge is evil. However, not all revenge is equal either.
Furthermore, there is righteous indignation, which is not evil. Those who do not know better, those who are the untaught masses deserve our mercy. However, those that know better not so much. Jesus often rebuked the Pharisees because they knew the law, but were external in their actions only.
Anyway. Hope you have a good day.
