Here's a challenge as you are still young: do something correct that still injures somebody.

A police officer may have to kill a citizen to execute his duty, but he will still feel badly about the death of the decedent.

A historian may write a necessary history, cause, inadvertently, some to lose their way, and still feel badly about that result.

We didn't exactly hear the speech, so we don't know how it was phrased. I have done many things which were necessary but still caused me sadness.
