True, don't throw the first stone if you haven't integrated your subconscious shadows that really are drawn to power as power means life.
Seek to integrate. Transcend your ego. Only then (if you still desire to do so) judge others.
That said we a live in today's world and it already takes a lot of courage to speak up against abusive behaviour that protects itself. Don't stop truth coming out of the shade. It is simply the first step to search for wrong doing outside of your own existence after waking up from ignorance.
