Classic Poem

Yes, others do it: wherefore may not I?
 They prosper, they enjoy, and never rue it—
Well, if they do not feel the acted lie,
'Tis little sin to do it.

But I both see and feel it deeply wrong,
 And thus the crime of doing it were deeper;
Nor I go scathless as the prosperous throng
That own no inward keeper.

'Tis not that in return the smitten smite,
 Nor that outflowing injury is tidal;
But evermore for him who sees the right,
The wrong is suicidal.
