Present day Internet's favorite Logic

Flawed logic: "A wrong done is not wrong because a similar wrong was done in the past by someone accusing you of wrongdoing"

Tail end : (My view)
It is beyond contention that right n wrong is relative. What may be right to you may be wrong to someone else.

But...

What you consider wrong IS wrong regardless of the fact that someone accusing you to be wrong had done the same wrong at some point of time in the past.

Accept our mistakes and move forward correcting it, rather than blindly denying it on loose grounds.
